Move trampolines to thumb2 instead of ARM
Currently the entrypoint trampolines are compiled using the ARM32 assembler.
This changes that to use the thumb2 assembler for consistency with the
other compiled code.

Thumb2 assembler for JNI compiler and optimizing compiler
This provides a programmatic assembler for the thumb2 instruction set for
ARM. The interface is the same as the ARM assembler and the ARM assembler has
been moved into Arm32Assembler. The assembler handles most 16 and 32 bit instructions
and also allows relocations due to branch expansion. It will also rewrite cbz/cbnz
instructions if they go out of range.
It also changes the JNI compiler to use the thumb2 assembler as opposed
to forcing it to use ARM32. The trampoline compiler still uses ARM due to the
way it returns the address of its generated code. A trampoline in thumb2 is the
same size as that in ARM anyway (8 bytes).
Provides gtest for testing the thumb2 instruction output. This gtest only runs
on the host as it uses arm-eabi-objdump to disassemble the generated code. On the
target the output is not checked but the assembler will still be run to perform
all its checks.

Now we have a proper C++ library, use std::unique_ptr.
Also remove the Android.libcxx.mk and other bits of stlport compatibility
mechanics.

AArch64: Fix the usage of IP0, IP1 as temporary registers
This patch fixes the usage of temporary registers by using VIXL's
UseScratchRegisterScope. For the primitives used by the trampoline
compiler we explicitly exclude IP0, IP1 from the temporary list.

Allow mixing of thread offsets between 32 and 64bit architectures.
Begin a more full implementation x86-64 REX prefixes.
Doesn't implement 64bit thread offset support for the JNI compiler.

Trampoline and assembly fixes for ARM64
Trampolines need a jump, not a call. Expose br in the ARM64
assembler to allow this.
The resolution trampoline is called with the Quick ABI, and will
continue to a Quick ABI function. Then the method pointer must be
in x0.

AArch64: Add arm64 runtime support.
Adds support for arm64 to ART. Assembler stubs are sufficient for
down calls into interpreter. JNI compiler and generics are not finished.
Basic Generic JNI functionality.

Enable annotalysis on clang ART builds.
Fix clang build errors aswell as restructure locking/mutex code for correct
thread safety analysis support.
Reorder make dependencies so that host builds build first as they should
provide better compilation errors than target.
Remove host's use of -fno-omit-frame-pointer as it has no value with correct
use of CFI, which we should have.

Fix host architecture for 64bit.
Also, hack x86 assembler for use as a x86-64 trampoline compiler's assembler.
Implement missing x86-64 quick resolution trampoline.
Add x86-64 to the quick elf writer.
