Improve performance of invokevirtual/invokeinterface with embedded imt/vtable
Add an embedded version of imt/vtable into class object. Both tables start at
fixed offset within class object so method/entry point can be loaded directly
from class object for invokeinterface/invokevirtual.

AArch64: Add memcmp16() for Arm64; ensure xSELF not clobbered
This patch modifies memcmp() to memcmp16(). Please note that this
implementation of memcmp16() is based on the bionic's memcmp().
However, to reflect a recent specification change, the file has been
modified to respect the new String.compareTo() behavior.
A test for memcmp16() has been added. The string_compareto test in
stub_test has been changed to invoke __memcmp16 in assembly stubs.
Add artIsAssignableFromCode to the list of native downcalls to
store and reload x18. Remove CheckSuspendFromCode, as it is unused.

ART: Move __memcmp16 from Bionic to ART
Handle __memcmp16 / MemCmp16 in ART. Import assembly implementations
for arm and mips from Bionic. Use a generic C version for all other
platforms.
Removes the memcmp16 quick entrypoint, as it is never used. Bump
the oat version and update thread.cc and checks to reflect the
structural change.

Art compiler: remove unnecessary sqrt call
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
compiler inherited this behavior. It is not necessary, and the CL
purges it (along with the out-of-line sqrt entrypoint).

This patch:
- removes unused stubs in x86/64 runtimes (art_quick_l2d, art_quick_l2f
and art_quick_idivmod)
- replaces art_quick_fmod, art_quick_fmodf and art_quick_is_assignable
entrypoints in x86-64 to the direct calls
- removes art_quick_indexof stub in x86-64

Guard entrypoint changing by runtime shutdown lock.
There was a race when we changed the allocation entrypoints where a
new thread would be starting (Thread::Init) and initialize to the
wrong entrypoints. Guarding allocation entrypoint changing
with the runtime shutdown lock fixes this race condition since
Thread::Init is only called with the runtime shutdown lock held.

Refactor allocation entrypoints.
Adds support for switching entrypoints during runtime. Enables
addition of new allocators with out requiring significant copy
paste. Slight speedup on ritzperf probably due to more inlining.

that the switch statement in the allocation code is optimized
out.

Improve quick codegen for aput-object.
1) don't type check known null.
2) if we know types in verify don't check at runtime.
3) if we're runtime checking then move all the code out-of-line.
Also, don't set up a callee-save frame for check-cast, do an instance-of test
then throw an exception if that fails.
Tidy quick entry point of Ldivmod to Lmod which it is on x86 and mips.
Fix monitor-enter/exit NPE for MIPS.
Fix benign bug in mirror::Class::CannotBeAssignedFromOtherTypes, a byte[]
cannot be assigned to from other types.

Split the allocation path into 'instrumented' and 'uninstrumented'
ones.
The instrumented path is equivalent to the existing allocation path
that checks for three instrumentation mechanisms (the debugger
allocation tracking, the runtime allocation stats collection, and
valgrind) for every allocation. The uinstrumented path does not
perform these checks. We use the uninstrumented path by default and
enable the instrumented path only when any of the three mechanisms is
enabled. The uninstrumented version of Heap::AllocObject() is inlined.
This change improves the Ritz MemAllocTest by ~4% on Nexus 4 and ~3%
on Host/x86.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.
