Quick: Create GC map based on compiler data. DO NOT MERGE
The Quick compiler and verifier sometimes disagree on dalvik
register types (fp/core/ref) for 0/null constants and merged
registers involving 0/null constants. Since the verifier is
more lenient it can mark a register as a reference for GC
where Quick considers it a floating point register or a dead
register (which would have a ref/fp conflict if not dead).
If the compiler used an fp register to hold the zero value,
the core register or stack location used by GC based on the
verifier data can hold an invalid value.
Previously, as a workaround we stored the fp zero value also
in the stack location or core register where GC would look
for it. This wasn't precise and may have missed some cases.
To fix this properly, we now generate GC maps based on the
compiler's notion of references if register promotion is
enabled.

Hiroshi Yamauchi [Thu, 21 May 2015 19:05:27 +0000 (12:05 -0700)]
Fix for potential moving GC bugs around proxy class.
- Handlerize proxy_class which is live across multiple allocation
points in ClassLinker::CreateProxyClass().
- In ClassLinker::CreateProxyClass(), insert a proxy class into the
class table before creating ArtFields for it (and update it later in
LinkClass()) because the field roots (ArtField::declaring_class_)
won't be updated by GC unless the class is in the class table. If GC
happens before they are updated by FixupTemporaryDeclaringClass()
from LinkClass(), FixupTemporaryDeclaringClass() may not update the
field roots correctly because the old class may already be moved but
the fields roots may not. Reduce a window of time where the fields
roots could be stale.
- In ClassLinker::LinkClass(), directly wrap a new class in a handle
to avoid a window of time where new_class may be potentially stale.
- Print more diagnostic info about the holder of the field upon a mark
sweep invalid ref crash.
- Add an additional sanity check in Field::GetArtField().
