This is a quick hack to remove ASan annotations from SANITIZE_TARGET
build, because they are breaking everything - it looks like we forget
to clean redzones from a page before releasing it to the system, and
some unrelated code runs into them later.
We will add some way to control this from the build system later,
or just fix the underlying issue and re-enable by default.

ART: JNI thread state transition optimization
This patch improves the JNI performance by removing the explicit acquiring and
releasing the mutator lock when a thread state transits between suspended and
runnable states.
The functions responsible for changing the state were found to be the costliest
part of the JNI. Originally, a thread needs to acquire a shared mutator lock by
a CAS instruction when entering the runnable state and also needs to release
the lock by a CAS when entering the native state from runnable. This patch
removes these CAS operations when a thread state transits between suspended and
runnable. A thread in the runnable state is considered to have shared ownership
of the mutator lock and therefore transitions in and out of the runnable state
have associated implication on the mutator lock ownership. Meanwhile, a barrier
is added to control suspending all threads from running.
JNI transition overhead was reduced by 25% on IA platform and by 17% on ARM
platform by this patch, while it has little impact on GC pause time (measured
with "suspend all histogram").

Thread-local mark stacks for the CC collector.
Thread-local mark stacks are assigned to mutators where they push
references in read barriers to reduce the (CAS) synchronization cost
in a global mark stack/queue.
We step through three mark stack modes (thread-local, shared,
GC-exclusive) and use per-thread flags to disable/enable system weak
accesses (only for the CC collector) instead of the existing global
one to safely perform the marking phase. The reasons are 1)
thread-local mark stacks for mutators need to be revoked using a
checkpoint to avoid races (incorrectly leaving a reference on mark
stacks) when terminating marking, and 2) we can’t use a checkpoint
while system weak accesses are disabled (or a deadlock would
happen). More details are described in the code comments.
Performance improvements in Ritzperf EAAC: a ~2.8% improvement
(13290->12918) in run time and a ~23% improvement (51.6s->39.8s) in
the total GC time on N5.

ART: Fix DexFileVerifier try_items OoO validation
DexFileVerifier::CheckIntraCodeItem() implements an out of order
validation for CodeItem try_items. try_items_size is validated for
sanity via CheckListSize() at dex_file_verifier.cc:800, although
handlers_size ULEB128 read (offset calculated from tries_size_) occurs
before at lines 797-798.
An out of bounds (wild) read will occur for invalid try_items_size at
parsed DEX file.
handlers_size read has been moved after try_items validation to resolve
this OoO issue.
