The new implementation moves away from desugaring of async
functions on kernel AST, state machine generated in the flow graph and
capturing all local variables in the context.
Instead, async/await is implemented using a few stubs
(InitSuspendableFunction, Suspend, Resume, Return and
AsyncExceptionHandler). The stubs are implemented in a
platform-independent way using (macro-)assembler helpers.
When suspending a function, its frame is copied into a SuspendState
object, and when resuming a function it is copied back onto the stack.
No extra code is generated for accessing local variables.
Callback closures are created lazily on the first await.

Previously VM had a hardcoded constant values for context indices of
_future variables in _Future.timeout and Future.wait (used while
collecting stack traces). As those variables are allocated in
the context after captured parameters, their indices depend on
whether the parameters are captured.
I'd like to improve tree shaking so that it will remove
part of Future.wait method and make one of the parameters
not captured, which changes the context index (and it may vary
between modes and for different programs).
So, instead of hardcoding those indices, they are now calculated
at compile time and stored in ObjectStore. This is more flexible
and accommodates for future changes in tree shaker.

Attempts to run class finalizaton on background thread revealed the problem where during optimization(which could run on mutator thread too) we might need to finalize previously unseen class, load annotatons for it, load and set some constant fields. This could result in updating Fields guarded_cid, requires check during installation of newly produced optimized code. Because mutator thread is currently exempt from cloning and validating fields guards, that could result in invalid optimized code installation.
This CL ensures that fields are always cloned in optimizing compiler even when it runs on mutator thread.
Ability to run multiple optimizing compilers is also needed for dartbug.com/36097.

This is a reland of 42c76fd910
Main issue was due to the parameter order of the invoke field dispatcher
not matching the argument order described by its saved arguments
descriptor. There's no reason for it not to, so now it does.
Also fixes some issues with stack trace tests that failed due to
increased deduplication of closures by forbidding deduplication for
those tests.
TEST=Run on trybots of all architectures as well as flutter engine

These checks are now performed in the dynamic closure call dispatcher.
To avoid having to create type argument vectors (TAVs) for default type
arguments at runtime, we cache a compile-time created TAV in the
ClosureData for the closure function which is retrieved by the
dispatcher when needed.
We also keep an associated packed field of information that can also be
determined at compile time:
* Whether the cached TAV needs instantiation or can share its
instantiator or function type arguments.
* The number of parent type parameters.
The former allows the generated IL to keep the invariant that the
InstantiateTypeArguments instruction (and the runtime entry it calls) is
only used for uninstantiated TAVs.
Also changes the destination name to an Value input for the
AssertSubtype instruction and adds handling for non-constant types and
names in that instruction's backend.
Additional changes:
* Adds new slots for ClosureData, Function, and TypeArguments.
* Adds a new kUnboxedUint8 representation (needed for
TypeParameterLayout::flags_, which is of type uint8_t).
* Extends LoadField to handle uint8_t unboxed native fields.
* Adds BoxUint8 for boxing unboxed uint8_t values.

Previously, we only loaded the default arguments for type parameters
(those used when instantiating to bounds because no explicit type
arguments were provided) directly from the kernel at compile time to
generate default type argument handling for function code. Thus, the
only trace of the default type arguments at runtime were code constants,
and there was no way to access them if needed in the runtime. This means
for runtime checks, like in Function::DoArgumentTypesMatch, we ended up
creating our own instantiate-to-bounds implementation.
Instead, read the default arguments for type parameters and store them
when creating TypeParameter objects. This allows the runtime to use the
default type argument information provided by the front end, ensuring we
don't need to maintain our own instantiate-to-bounds implementation.
This adds only a slight overhead to snapshot size. Using the Flutter
gallery in release mode for example:
* arm7: read-only data: +0.05%, isolate: +0.04%, total: +0.02%
* arm8: read-only data: +0.00%, isolate: +0.04%, total: +0.01%

Instead of possibly looping over the closure function parameter names
array multiple times, just do it once. Check each entry against the
provided argument names. If none match, check the required bit (if in
null-safe mode). Also keep a count of matched names to check that all
provided names matched after the iteration.
Now that optional name checking is part of the fragment built by
BuildClosureCallArgumentsValidCheck, that method builds checks for
exactly the same things as its namesake in Function.
Also refactor the variables used by the checker into read/write ones
that need to be allocated in the parsed function and read-only ones
that can just be temporaries since no Phi nodes are needed.

This CL performs the following checks in the invoke field dispatcher for
dynamic closure calls when lazy dispatchers are enabled:
* The provided function type arguments vector (if any) has the correct
length.
* No function type arguments should be provided if the closure has
delayed type arguments.
* All required arguments (positional in all modes, named in appropriate
null safety modes) have been provided by the caller.
* If there are optional positional arguments, an appropriate number
has been provided.
* If there are optional named arguments, their names are valid.
Since the runtime already handles checking the argument shapes when lazy
dispatchers are disabled, these checks are now completely removed from
closure bodies in all cases. Thus, the only remaining checks in closure
bodies are the type checks performed by AssertSubtype and
AssertAssignable when lazy dispatchers are enabled.
Changes in the Flutter Gallery:

* language{,_2}/parameter/named_with_conversions_test
* language{,_2}/vm/no_such_args_error_message_vm_test
I've added one test to specifically check the interaction between
dynamic calls and required named parameters. There is some coverage in
other NNBD tests, but those are not directly focused on testing this
specifically.
Other changes:
* Adds initial cached ranges for certain BinarySmiOp and ShiftIntegerOp
instructions when the RHS is a constant, to avoid false negatives for
deoptimization and throw checks prior to range analysis.
* Adds new slots for various Function fields.
* Adds the ability to define unboxed native slots, which are always
unboxed after retrieval even in unoptimized code. In the first
iteration, the backend only handles loads from Uint32 unboxed native
slots. Part of https://github.com/dart-lang/sdk/issues/42793.
* Removed the special handling for loading from non-nullable int fields
in AOT compilation. Instead, their treatment is unified with the
treatment of the new unboxed native fields, since the source field is
always unboxed and the result of the load is also always unboxed, as
code involving them is always optimized.

This CL also introduces convenience ParsedFunction::ParameterVariable()

We say that field's static type G<T0, ..., Tn> is exact if for
any value that can be loaded from this field, its runtime type
T is such that T at G has type arguments exactly equal to
<T0, ..., Tn>.
Know if field's static type is exact allows us to apply optimizations
that require knowing type arguments e.g.
- we can fold o.f.:type_arguments
to a constant value if we know that o.f is trivially exact;
- for method invocations o.f.m(...) we can skip argument type checks
on the callee if we know that o.f is invariant (this optimization will
be enabled once multiple entry points CLs will land).

The original revision is in Patchset 1.
Due to idiosyncrasies of the legacy VM parser, we need to put the @pragma definition
on both the original and patched definition. Hopefully we can remove these extra definitions
once Dart 1 AOT is fully obsolete.

This CL continues refactoring aimed at isolating StreamingFlowGraphBuilder.
StreamingFlowGraphBuilder dependency is removed from classes
* StreamingConstantEvaluator (it still depends on FlowGraphBuilder)
* ConstantHelper
* SimpleExpressionConverter
and several methods in object.cc.
StreamingConstantEvaluator and ConstantHelper are moved from
kernel_binary_flowgraph{.h, .cc} to a new source file
constant_evaluator{.h, .cc}. StreamingConstantEvaluator is renamed
to ConstantEvaluator.
KernelFingerprintHelper and KernelSourceFingerprintHelper are moved to
a new source file kernel_fingerprints{.h, .cc}.
Instances of kernel::FlowGraphBuilder no longer contain back reference
to a StreamingFlowGraphBuilder. In order to drop this circular dependency
TranslateFinallyFinalizers() is moved from FlowGraphBuilder to
StreamingFlowGraphBuilder.

After previous refactoring, StreamingScopeBuilder no longer depends on
StreamingFlowGraphBuilder.
This CL moves StreamingScopeBuilder to a separate file
vm/compiler/frontend/scope_builder{.h, .cc}.
Also:
* StreamingScopeBuilder is renamed to ScopeBuilder.
* IntMap is moved to hash_map.h.
* Minor cleanup of unused forward declarations and friend classes.
