Builds on top of https://dart-review.googlesource.com/c/sdk/+/228660, introduces vm:vm:always-consider-inlining that tell inliner not to give up inlining of a function.
HashMap constructor got prefer-inline pragma to accommodate shift in inlining away from where it used to be inlined due to large size of inlined HashMap, greater than FLAG_inline_getters_setters_smaller_than heuristic.

Instead of using an integer literal use constexpr popcount
function instead.
The misalignment causes an incorrect generation of a call
to a shared write barrier stub for the last allocatable register
on ARM64.

The unified base class for instructions with variable number of inputs
now keeps inputs in GrowableArray<Value*> (no indirection, no extra zone
memory allocation).
InputsArray is changed to GrowableArray<Value*> instead of
ZoneGrowableArray and passed as rvalue reference.

Heap snapshots currently produced don't visit isolate stacks. As such
analyzing such snapshots may lead one to conclude there is a lot of
garbage while objects are actually reachable.
=> This CL makes us visit isolate stacks when building heap snapshots.
Furthermore we add a new `VMInternals.writeHeapSnapshotToFile` helper
that can be used to programmatically write snapshots and can be handy
for internal use at times. (We also use this helper in a test)

(Running on linux-x64c)
os: macos arch: arm64 comp: no sim: yes

This CL also abstracts out the separate hardcoded strings across
the codebase for host and target OS and architecture into
definitions in platform/globals.h to ensure that they stay
in sync across different uses.

This change removes duplicate management of inputs in variadic
IL instructions by introducing VariadicDefinition and
VariadicDefinitionWithEmbeddedInputs base classes.
TemplateInstruction and TemplateDefinition are used in more
places where appropriate.
Number of inputs no longer depends on the values of the inputs
(DropTempsInstr and AllocateObjectInstr).
This change also prepares IL for the future implementation of binary
serialization/deserialization in the following ways:
* Environment now holds Function and not ParsedFunction
(which are not going to be serialized).
* Instructions no longer keep Zone* pointer (it's redundant).
* NativeCallInstr keeps references to handles instead of pointers.

In `use_flag_test_helper.dart`, there is code for SIMARM/SIMAR64,
but now we have SIMRISCV64.
For now, just look for `SIM` in the build directory to determine
whether or not we're running on a simulated architecture, and
disable the assembly part of `use_dwarf_stack_traces_flag_test.dart`
on all simulated architectures instead of just SIMARM/SIMARM64.
(They run fine locally for SIMARM/SIMARM64, but trybots don't
have the buildtools fetched currently as the configuration uses our
own ELF writer to generate snapshots, not an assembler.)

This is a reland of commit 08c13f173c
Fixes test failures on non-x64 architectures, both in the test
harness and due to DWARF5 line number program headers having a
non-backwards compatible format. (We generate DWARF2 in the
ELF snapshot writer, but the assembler used for assembly snapshots
may generate DWARF5.)

Previously there was a window between the decision to resume generator
and actually running the micro-task. The stream could be canceled
during that window, making running the generator incorrect.
The solution is to check if the stream was canceled right before
resuming the generator in yield/yield*.
This change also unifies yield and yield* to check if the stream
was canceled even before suspending the generator.
