As part of making lightweight isolates work in JIT, we will need to
ensure that whenever a new isolate is spawned it will get it's initial
global field table populated.
In order to achieve this we make the isolate groups initial field table
the authoritive place where we
a) register initial static field values
b) serializer reads them from, deserializer writes them to
This allows us to also remove the `FieldLayout::initial_saved_value_`
that was present for both static and non-static fields. In reality this
initial saved value is only meaningful for static fields though it was
kept in memory as well as (de)serialized even for non-static fields.
The one place where it was actually used for non-static fields was
incorrect and should instead use `null`.
The removal of this field results in net removal of code in this CL.

As part of making lightweight isolates work in JIT, we will need to
ensure that whenever a new static field is loaded, it will get a new
slot on every isolate and the possibly initial static value is set in
all isolates's field state.
In order to achieve this we first move field registration out of
Field::New*() - to the place where the field is created and the initial
static field value is known.
In a future CL we will make a field registration be performed on all
isolates in a group.
TEST=CL is internal refactoring, existing test coverage.

This disables field unboxing in JIT with enabled lightweight isolates because currently unboxed generated code won't behave correctly if another isolate updates field unboxed state: for that guarded_cid updates would require stopping all isolates, getting to a safepoint.
Use of field guards(guarded_cid, is_nullable) in optimized compiler is concurrent-safe because each optimized compiler operates on its own clones of fields, which are checked for consistency with latest(mutator) state just before optimized code is installed.
Use of field guards in optimized generated code is safe because vm is brought to a safepoint and optimized code is deoptimized as soon as field guards are invalidated.
Use of field guards in generated unoptimized code outside of unboxed fields(transition to boxed from previously unboxed field is not safe which is why field unboxing is disabled) and use of field guards in unoptimized compiler is safe because transitions through guarded_cid and is_nullable makes less and less optimistic assumptions about the field state.

This CL extends SubtypeTestCache entries with an additional slot that
contains the type being checked, to allow for future uses where
different runtime types can flow through a single checkpoint. This
change is separated from those future uses to determine the impact of
these changes only.
Thus, most SubtypeTestCache checks require the type as an additional
argument, and now the destination type register in TypeTestABI is now
untouched in SubtypeTestCache checks. Since there are currently no plans
for a dynamic InstanceOf test, the one argument SubtypeTestCache is left
unchanged.
Until we add cases in later CLs where the type can differ at the same
AssertAssignable instruction, we could check the type last since it is
currently guaranteed to be the same each time. However, we instead check
it after the instance, which is when it should be checked once we have
AssertAssignable instructions with types only known at runtime. This
avoids having to change it later, but also ensures the measured impact
of these changes can be compared to the impact of later changes.
In addition, this CL also unifies most of the code used by
GenerateInstanceOf (and also GenerateAssertAssignable via
GenerateInlineInstanceof on IA32). This is possible since register use
changes in the helper functions has eliminated the need to push the
instantiator and function type argument registers from TypeTestABI on
non-X64 architectures. By unifying these methods, we ensure that all
architectures appropriately set TypeTestABI::kDstTypeReg when necessary.

The only architecture-specific part of type testing stubs (TTS) is which
registers get saved/restored across SubtypeTestCache stub calls in the
slow TTS implementation, which is now a register mask constant in the
TypeTestABI struct.
This CL also:
* Creates a single definition of OperandSize in assembler_base.h. Moves
OperandSize into the compiler namespace. assembler_base.h. Renames
constants common to all architectures to neutral names (e.g., kWord =>
kFourBytes), since "word" has different meanings across architectures.
* Creates a new JumpDistance enum for kNearJump/kFarJump in
AssemblerBase and replace existing bool uses with the constants.
* Adds JumpDistance arguments to some of the generalized Assembler
methods so they aren't forced to use far jumps on IA32/X64. These

We were mixing and matching `TARGET_OS_IOS` and `TARGET_OS_MACOS_IOS`.
The former is defined by Xcode and not by our own defines leading us to
not actually unit test the iOS calling convention.

Before `dart run` would always use the package config found by looking up the hierarchy from
whatever we got from getExecutableForCommand.
When that happened to be a precompiled snapshot this would work, because it would be ignored.
But if it would be a dart-file in another package (that would happen if that package is not cached)
we instead should resolve it relatively to the current working directory
(where the pubspec.yaml is also found).

Since the transition from Source based to Kernel based frontend to the
Dart VM, we have not supported callable redirecting factories. This has
caused all removed code in this CL to be unused and untested!
The support for reifing redirection related information would mainly be
used by embedder / dart:mirrors. Right now its not used by anyone and
the kernel support was never implemented.
I suggest we remove the unused and untested code until a decision has
been made that we actually want to support it - in which case it can be
properly implemented, possibly by re-using some of the deleted code in
this CL.
TEST=CL removes unused code, no test result changes.

This CL introduces unit tests for the Native* classes in compiler/ffi
that can run for all supported target ABIs on any host architecture.
The unit tests are compiled for all target ABIs with
`tools/build.py run_ffi_unit_tests` and run for all target ABIs with
`tools/test.py ffi_unit`.
The unit test and tested code do not conceptually depend on having a
DartVM. The tests are compiled with a custom `dart::Zone` and
`platform/`. This enables compiling for all `TARGET_ARCH_*` and
`TARGET_OS_*` on any host, and running unit tests for all target ABIs
on any host.
Because the `run_ffi_unit_tests` executables do not include the DartVM
their build is quick (<10seconds) and they are small (~6MB) when
compared to `run_vm_tests` (~250MB).
The tests are added to the existing FFI QEMU bot to prevent adding an
extra bot which would add checkout overhead.
The unit tests themselves are set up to be fairly similar to vm/cc
tests. The only difference is the NativeCallingConvention tests which
are set up with `.expect` files for easy inspection and updating.

Adds a @pragma("vm:recognized", <kind>) to all recognized methods, where
<kind> is one of "intrinsic", "graph" or "other", corresponding to the
kind of recognized method.
When running in debug mode, it is checked that all recognized methods
are marked with the correct kind of pragma, and that all methods marked
with the pragma are in fact recognized.
This enables kernel-level analyses and optimizations to query whether
a method is recognized by the VM.

Use of PositionalCount() and PositionAt() as indices in the arguments
array must account for the type arguments if present. Otherwise, we'll
either skip checking the last positional argument (in the former case)
or check against the wrong arguments (in the latter case).
In nosuchmethod_forwarding_arguments_test.dart, add cases that check for
the above mistakes.
In require_named_args_strong_test.dart, use the more specific
throwsTypeError or throwsNoSuchMethod checks instead of the generic
throwsError to ensure the correct error is thrown.

The Isolate.spawn() is part of our dart:isolate library implementation,
it should therefore preferrably live under runtime/lib folder.
This CL does that as well as removing some special message handling
logic by using the new `Dart_RunLoopAsync()` C API, which results in
net removal of code.
As a nice side-effect it also makes isolate spawning slightly faster due
to avoiding extra safepoint/vm<->native transitions.

This reverts commit cda994ffc8.
Reason for revert: This stopped all sending of analytics from dartdev.
The added flag in dartdev had an implicit default value of 'false' -> no analytics would be sent.
Also the main_options.cc change was broken and did not pass the argument on to dartdev.
This failed to be caught by tests because all test are run with analytics off, and that happened implicitly.
