Replace intptr_t with TokenDescriptor
...
- Use TokenDescriptor instead of intptr_t for all token positions.
- Use TokenDescriptor in raw_object instead of int32_t.
- TokenDescriptor is a POD with an int32_t (this shrinks the size of AST and IR nodes by 32-bits on 64-bit architectures).
There are some cleanups I plan on doing as a follow up CL:
- Replace TokenDescriptor::value() with TokenDescriptor::TokenPos()

Implement safepointing of threads :
...
- 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.

Make CTX allocatable by the register allocator.

This change makes CTX available by not caching the current
context while in Dart code. Instead the current context
is held in a local variable (:saved_current_context_var) and
is passed as argument in CTX at calls.
This also simplifies a lot of code in the debugger: As a result,
Isolate::top_context is not needed anymore since the current context
can always be extracted from a Dart frame.

Mark native functions when they are created.

Until now the parser marked native functions as native when parsing.
This may be too late for some functions. E.g. the native typed list
constructor may not be invoked because the intrinsic code is executed
instead (unless for example new-space allocation fails).
This causes missing type information when optimizing functions using
those recognized factory functions like Uint8List._new.

Update VM to latest spec. Referencing a name that is imported

If one of the sources of an ambiguous reference is a dart library,

Also fixes a bug where looking up a getter name in a library
found the getter even though the name is filtered out in the

Long-term we should fix the need for repeatedly convert between
the mangled getter and setter names and the untangled name.

Use the location summary to represent safepoint information.
...
Pass a LocationSummary everywhere instead of a BitmapBuilder. The
LocationSummary contains information about live registers.

Give a length field to stack bitmaps.
...
The bitmaps describing the stack have an explicit length field. It is now
an assertion failure to read bits outside the length --- they are no longer
assumed to be false.
Also remove an unused method and simplify the implementation of
BitmapBuilder by removing an embedded member that was always referred to via
a pointer.

Make stackmaps store their actual length.
...
This allows stackmaps with varying lengths in the same function, necessary
for the way we plan to support bitmaps for saved live registers.

Reduce space used for stackmaps.
...
Only allocate space for the bits covered by the stackmap, instead of
for the backing store of the utility class that built it. Fix a bug
where the size in bytes was multiplied by the word size in bytes.
Also do some cleanup of the stackmap code and renaming in the tests.

Associate the correct type to method receivers (instead of Dynamic type).
...
Properly name the first implicit parameter to factories as ':type_arguments'
(instead of 'this', which made it accessible to user code).
Various cleanup.

Consolidate a few fields in RawFunction using bitfields.
...
Remove kAbstract from the list of function kinds. It now has its own
dedicated bit. This allows us to distinguish abstract methods from
abstract getters and setters.
