Vyacheslav Egorov a9ce969e53 [vm] Decouple growable_array.h and zone.h from thread.h
- Introduce a slimmed down version of thread.h, which just depends on the
Zone and StackResource.
- Introduce a layering check that would prevent the coupling in the future.

This is the first step towards decoupling compiler from runtime.

There are multiple reasons to introduce the decoupling but the main
reason currently is to introduce a controlled surface through which
compiler reaches into runtime to catch any places where runtime word size
might influence the compiler and then enable building compiler that
targets 32-bit runtime but is embedded into a 64-bit runtime.

Ryan Macnak fa6a1684ef [vm] Introduce a separate VMTag for the interpreter.
Makes time spent in interpreted versus compiled Dart code visible in Observatory's pie chart. Will allow the profiler to know whether to start a stack walk from the machine code FP or the interpreter's FP.

Remove dead Dart 1 frontend tags. Add tag for loading bytecode.

Ryan Macnak 877284947b Rename TARGET_OS_* to HOST_OS_*.
Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.

Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

Siva Annamalai 9e19d236ca - Add an OSThread structure which is the generic TLS structure for all C++
fields in a thread (i.e fields that are not Dart VM related)
- Split the Thread structure to be a pure Dart per thread structure and add
  a pointer to os_thread which points to the OSThread structure
- Change Schedule/UnSchedule to set the Dart Thread structure as the TLS of
  the thread when it is inside the Dart world and reset the TLS back to the
  OSThread strcuture when is exits the Dart World.
- Moved the stack_base and few stack size related functions to OSThread from Isolate

John McCutchan ceb12c4f69 Switch profiler from isolates to threads
- API breakage: Dart_IsolateBlocked, Dart_IsolateUnblocked -> Dart_ThreadDisableProfiling, Dart_ThreadEnableProfiling.
- Remove IsolateProfilerData.
- Move thread at blocking call count from isolate to thread.
- Always interrupt threads unless they are blocked.
- We can no longer count "idle" ticks.
- Only record sample if thread is the current mutator of an isolate.
- Refactor ThreadInterrupterCallback to ensure that Thread* is valid.

Threads are only ever sent signals if ThreadInterruptsEnabled is true. Which is controlled by two functions:

void DisableThreadInterrupts();
void EnableThreadInterrupts();

zra@google.com 816bf5af2e Fixes for the profiler on arm64.
On arm64, in Dart code, R18(SP) is the stack pointer.
In C++ code, R31(CSP) is the stack pointer.
The profiler must choose the right one when performing
its bounds checks.

This change also fixes a bug in the InvokeDartCode stub
on arm64 so that CSP is set to the Isolate's stack
limit immediately, rather than a bit later. When it was
set a bit later, if a profiler interrupt came in in the
interim, the stack would be smashed.

vegorov@google.com d30ecd3fcd Fix Win64 build of Dart VM.
1. Build script tools/build.py now actually builds X64 target when x64
is passed as an architecture:

- GYP files set 'msvs_configuration_platform': 'x64' for Win_x64
configuration;

- NSS related files are fixed to have correct set of defines for ia32
and x64 builds and include right files. A os_windows.c file added to
work-around inability to have different sets of source files per
configuration. Originally this was controlled through target_arch GYP
define and required regeneration of the solution.

- build.py passes Win32 or x64 platform to devenv as part of build
configuration argument;

2. Dart VM now supports Win64 ABI. ABI description is moved into a
separate class CallingConventions in constants_x64.h.
