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.

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.

Support the double forms of:
cos, sin, acos, asin, atan, atan2, cbrt, cosh, exp, expm1,
hypot, log, log10, nextAfter, sinh, tan, tanh

Add these entries to the vector addressed off the thread pointer. Call
the libc routines directly, which means that we have to implement the
native ABI, not the ART one. For x86_64, that includes saving XMM12-15
as the native ABI considers them caller-save, while the ART ABI
considers them callee-save. We save them by marking them as used by the
call to the math function. For x86, this is not an issue, as all the XMM
registers are caller-save.

Other architectures will call Java as before until they are ready to
implement the new intrinsics.

Bump the OAT version since we are incompatible with old boot.oat files.

0d5a281c671444bfa75d63caf1427a8c0e6e1177 13-Nov-2015 Roland Levillain <rpl@google.com> 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).

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.

e295e6ec5beaea31be5d7d3c996cd8cfa2053129 07-Mar-2015 Mingyao Yang <mingyao@google.com> Deoptimization-based bce.

A mechanism is introduced that a runtime method can be called
from code compiled with optimizing compiler to deoptimize into
interpreter. This can be used to establish invariants in the managed code
If the invariant does not hold at runtime, we will deoptimize and continue
execution in the interpreter. This allows to optimize the managed code as
if the invariant was proven during compile time. However, the exception
will be thrown according to the semantics demanded by the spec.

The invariant and optimization included in this patch are based on the
length of an array. Given a set of array accesses with constant indices
{c1, ..., cn}, we can optimize away all bounds checks iff all 0 <= min(ci) and
max(ci) < array-length. The first can be proven statically. The second can be
established with a deoptimization-based invariant. This replaces n bounds
checks with one invariant check (plus slow-path code).

For reasons lost in the mists of time, the Dalvik JIT tested
the results of an inlined sqrt for NaN on Arm targets, and then
called an out-of-line routine to recompute if true. The Quick

purges it (along with the out-of-line sqrt entrypoint).
