Alexander Markov ebb7e1061c [vm] Use _setjmp instead of setjmp on MacOS/iOS
setjmp is extremely expensive on MacOS/iOS as it always saves
signal mask.

Introduce DART_SETJMP / DART_LONGJMP macros to use _setjmp instead of
setjmp on MacOS/iOS.

DeltaBlue on Mac/arm64 on the interpreter:
179585.3 us -> 58347.9 us. (3x faster)

Martin Kustermann 9bdd2ff1de [vm] Cleanup unused include, unnecessary fields on [Thread], rename mutator thread, ensure setjmp drains sticky error
Some cleanups factored out of a larger CL (which refactors enter/exit of threads):

  * remove unused `#include "vm/thread_registry.h"`
  * remove unused/unnecessary fields from [Thread] object
  * rename IsMutator() -> IsDartMutator()
  * make tests using setjmp() drain the sticky error
    => to ensure there's no sticky error on isolate shutdown

Ryan Macnak 14db718ed5 [vm] Add missing safepoint transitions.
Mostly tests; 1 non-test bug in propagating an error through Dart_SetReturnValue.

This is progress towards asserting thread->excution_state() == kThreadInVM in Object::Allocate.

Ben Konyi f2fd150ea0 Added new type of unit test, RAW_UNIT_TEST_CASE, which is used for tests that can be flaky if run while the VM is alive. Tests created using the RAW_UNIT_TEST_CASE macro will run after the VM has shutdown to avoid having any worker threads contaminating the test results.

zra@google.com fdeff1ba17 Replaces LongJump with LongJumpScope.
LongJump required explicitly restoring the old
long jump base before function return. This was
sometimes forgotten, leading to crashes. This
change puts the base restoration into the
destructor so that it happens automatically on
return.

turnidge@google.com 53ba5c402e Make the "sticky error" an Error instead of a String.
I do this in preparation for using the sticky error to implement
isolate unwinding.

sgjesse@google.com bf67f24098 Move assert.h/assert.cc from runtime/vm to runtime/platform
The purpose of this change is twofold:

1. Source in the bin directory can now use the same assertions as
   source in the vm directory. The ASSERT macro used by the code
   in runtime/bin was just defined to use assert from the standard
   C library.
2. Moving other implementation parts from runtime/vm to
   runtime/platform (e.g. classes Monitor and Mutex) for sharing
   between runtime/bin and runtime/vm will be easier as these
   implementations rely on these assertion macros.

Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.

All the code for asserts is still in the dart namespace.

Also re-arranged the order of includes to be alphabetically in
the files touched.
