Ryan Macnak c8dea19836 [vm, gc] Reserve some memory to use during handling of OutOfMemoryErrors.
This reserved space can only be allocated from after an allocation has failed from OutOfMemory, and once some portion of this space is used, refilling it is the first allocation performed after GC.

Also avoid greatly slowing down from ineffective scavenges as the memory limit is reached.

Alexander Markov bf968d5627 [Test] Remove vm/dart/il_round_trip_deserialization_test
This test was added a while ago during development of IL serialization
and deserialization (https://github.com/dart-lang/sdk/issues/36882),
which wasn't completed.

Since development of serialization/deserialization was put on hold,
this test was failing with a lot of flakiness, flipping between
Crash/Timeout/RuntimeError on unrelated changes (https://github.com/dart-lang/sdk/issues/43617,
https://github.com/dart-lang/sdk/issues/43359, https://github.com/dart-lang/sdk/issues/36882),
and even turning bots purple (https://ci.chromium.org/p/dart/builders/ci.sandbox/vm-kernel-precomp-nnbd-linux-debug-simarm_x64/32).

There are no signs that underlying problems with IL serialization/deserialization
are going to be addressed, but this test requires constant attention.
If implementation of https://github.com/dart-lang/sdk/issues/36882 is
ever resumed, it would be possible to resurrect this test from git history.

Tess Strickland 8f5f6971a9 [vm/compiler] Unify GenerateAssertAssignable on non-IA32 archs.
The differences between the different implementations are very
minor, so abstract out the few that remain into Assembler:

* Change Load<X>FromPoolOffset to Load<X>FromPoolIndex and do pool
  offset calculations internally, since all caller sites have the pool
  index. (Especially important because the pool register is tagged on
  X64 and ARM and untagged on ARM64, so this abstracts that away.)

* Add default for pool register argument on ARM, since ARM64 already had
  one and X64 doesn't take a pool register argument.

Other changes:

* Use specific TestTypeABI registers within the helper method that adds
  caller-side checks instead of passing registers as arguments and
  document which registers are used for input or output (and when, if
  they are used conditionally).

When loading a late field without initializer, we check if it was not

if supported) for throwing LateInitializationError instead of calling
an initializer which would throw an exception. This improves register
allocation around accesses to such late fields.

In addition, this CL removes duplicated code for generating shared
stubs.

Tess Strickland d9685d1c4c [vm/compiler] Move type argument type checks out of closure bodies.
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.

Code size impact on Flutter gallery in release mode:

* arm7: total +0.08%, vmisolate: +0.56%, isolate: +0.42%,
        readonly: -0.04%, instructions: -0.03%

* arm8: total +0.12%, vmisolate: +0.56%, isolate: +0.42%,
        readonly: -0.002%, instructions: +0.03%

Daco Harkes 957487b5da [test/ffi] Structs by value 1-byte aligned
The 3 and 7 byte tests in
https://dart-review.googlesource.com/c/sdk/+/168829
had their sizes rounded up to the next power of two due to alignment of
fields inside the structs.

In order to properly exercise behavior on win32, win64 and iOS, this CL
changes those structs to only have uint8 fields to prevent alignment
influencing the sizes.

Old tests are renamed to exercise the size rounding due to alignment.

This also swaps around the two 9byte structs to have consistent naming
with the new 3 and 7-byte tests.

structs_by_value_tests_confguration.dart is the only non-generated file.

The tests are tested in the dependent CL. Tests are ignored in status
file and are un-ignored in dependent CL.

Tests for https://github.com/dart-lang/sdk/issues/36730.

Tess Strickland 264730e28d [vm] Store default arguments in TypeParameters.
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%

Tess Strickland b64d20e434 [vm] Print symbol names and offsets in simulator backtraces.
When running the simulator on precompiled mode, source information
is lost, so only the filename is valid with the line and column
information printed as -1.  For each frame, this CL adds the symbol name
of the instructions section and a hexadecimal offset from the start of
the section, which can be used with the native_stack_traces package. The
absolute address of the VM and isolate instructions are also included
at the start of the backtrace.

Allow weak tables to contain immediate objects (Smis) by adjusting the sentinel value for an empty entry to a value which is never a valid Smi nor heap object. Immediates go into the old-space table, since they also don't need to be updated after a scavenge.

Remove the clustered serializer's separate Smi id table.
