- Modify toDart to first do a simple lookup in the appropriate table before going down the templatized
...
morass of switch statements
- Add a returnToDart function so that the WeakPersistent Handle returned from a lookup/create of the wrapper
could be returned as is without the need to call Dart_handleFromWeakPersistentHandle
- Use Dart_SetDoubleReturnValue for doubles

Update handling of ambiguous name references
...
Update VM to latest spec. Referencing a name that is imported
from more than one library is no longer a compile-time error.
If one of the sources of an ambiguous reference is a dart library,
the dart library declaration is automatically hidden.
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
'hide' combinator.
Long-term we should fix the need for repeatedly convert between
the mangled getter and setter names and the untangled name.
Fixes 12915, 12913, 12724.

1. Add flag --trace-api to trace API function invocation
...
2. Add tracing of external native functions under --trace-natives flag
3. Added a _printCurrentStacktrace() function so that one could get a
dart stack trace under 'gdb' when in a native or runtime function.
