i.e. #ifndef VM_WHATEVER -> #ifndef RUNTIME_VM_WHATEVER
This lets us remove a hack from the PRESUBMIT.py script that existed
for reasons that are no longer valid, and sets us up to add some
presubmit checks for the GN build.

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

- 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();

- InterruptableThreadState is gone.
- Moved InterruptableThreadState fields directly into Thread.
- Iterate over all threads in an isolate when profiling.
- Still only sample the mutator thread.
Fix ThreadRegistry leak
- When deleting a Thread, iterate over all isolates and remove it from the isolate's thread registry.

Move the field from Isolate to Thread::state_ to allow using a single thread local key.
Profiling is still only enabled for the Dart mutator thread.
The next step is to migrate the VM tags.

Profiler improvements:
- Track Functions in profile and build Function based trie
- Associate code objects with functions
- Created cpu_profile.dart library
- Major speed improvements for disassembly view
- Fix truncation of disassembly comments
- Ability to get code object ticks from disassembly view
- Inlining mini-map in disassembly view.
- Remove a bunch of unused data from profile service response
- In some cases a caller PC that is better than the PC marker is inserted into the stack trace
- Inlined functions are expanded
- Ability to clear profile
- New flag '--keep_code' which keeps deoptimized code around for use by the profiler.
General fixes:
- Fix caching in service library
- Remove pubspec.yaml before running pub get

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.
