X86: Assembler support for near labels
The optimizing compiler uses 32 bit relative jumps for all forward
jumps, just in case the offset is too large to fit in one byte. Some of
the generated code knows that the jumps will in fact fit.
Add a 'NearLabel' class to the x86 and x86_64 assemblers. This will be
used to generate known short forward branches.
Add jecxz/jrcxz instructions, which only handle a short offset. They
will be used for intrinsics.
Add tests for the new instructions and NearLabel.

2. In gdb, run 'b art::Class_classForName' which is implementation of a Java native method, then 'r'

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.
