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for reasons that are no longer valid, and sets us up to add some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.

in these blocks will not have a safepoint operation
- changed boxed_field_list_monitor_ to boxed_field_list_mutex_ as we only
need a mutex for guarding access to boxed_field_list_ as changed the
lock to use SafepointMutexLocker as the list addition code could potentially
allocate and result in GC (safepoint operation)
- Added a SafepointMonitorLocker as we have a function Isolate::VisitIsolates
which could potentially have safepoints in the enclosed block.
- Make the lock around MegamorphicCacheTable::Lookup a SafepointMutexLocker
as the look up code seems to be allocating memory while the lock is held.
- Changed the ThreadPool and MessageHandler code to account for the new
MonitorLocker usage standard
- Fixed PortMap::PrintPortsForMessageHandler to use SafepointMutexLocker as
the code it encloses calls into Dart
- Removed profiler_ field in class Profiler as it doesn't seem to be used.

- uses thread execution status transition to track when a thread is in a safepoint or needs to block for a safepoint
- introduces a monitor per Thread object
- uses a per thread safepoint handshake between the thread requesting a safepoint and the requested thread.
The ThreadRegistry class now contains only the thread list for an isolate and the functionality of scheduling a thread onto an Isolate and unscheduling it from teh isolate. We could fold this functionality into the Isolate class in a different CL.
