ART: Log all monitor operations to systrace
Add a VLOG option ("-verbose:systrace-locks") to log all monitor
operations to systrace. This requires non-fastpath thread
entrypoints, and ATRACE tags for locking and unlocking.
Do a bit of cleanup to the entrypoint initialization to share
common setup.

x86 Baker's read barrier fast path implementation.
Introduce an x86 fast path implementation in Optimizing for
Baker's read barriers (for both heap reference loads and GC
root loads). The marking phase of the read barrier is
performed by a slow path, invoking a new runtime entry point
(artReadBarrierMark).
Other read barrier algorithms continue to use the original
slow path based implementation, which has been renamed as
GenerateReadBarrierSlow/GenerateReadBarrierForRootSlow.

x86/x86-64 read barrier support for concurrent GC in Optimizing.
This first implementation uses slow paths to instrument heap
reference loads and GC root loads for the concurrent copying
collector, respectively calling the artReadBarrierSlow and
artReadBarrierForRootSlow (new) runtime entry points.
Notes:
- This implementation does not instrument HInvokeVirtual
nor HInvokeInterface instructions (for class reference
loads), as the corresponding read barriers are not stricly
required with the current concurrent copying collector.
- Intrinsics which may eventually call (on slow path) are
disabled when read barriers are enabled, as the current
slow path infrastructure does not support this case.
- When read barriers are enabled, the code generated for a
HArraySet instruction always go into the array set slow
path for object arrays (delegating the operation to the
runtime), as we are lacking a mechanism to keep a
temporary register live accross a runtime call (needed for
the instrumentation of type checking code, which requires
two successive read barriers).

ART: Remove interpreter entrypoints
These are no longer used as entrypoints. Make them proper runtime
functions local to the interpreter.
Bump oat version.

Revert "Revert "Fix deoptimization with pending exception""
This reverts commit 6e2d5747d00697a25251d25dd33b953e54709507.
Fixes the deoptimization path from compiled code (generated by the
Optimizing compiler) by adding wrapper artDeoptimizeFromCompiledCode.
This wrapper, called through the matching assembler stub
art_quick_deoptimize_from_compiled_code, pushes the deoptimization
context just before deoptimizing the stack.

Add read barrier support to the entrypoints.
Also remove "THIS_LOAD_REQUIRES_READ_BARRIER" since reading
an ArtMethod* no longer needs read barrier.
stub_test should also work with read barriers now.
