Utilizes r0..r7 in register allocator, implements spill/unsill
core regs as well as operations with stack pointer.

The arm backend clone is changed to produce A64 code. At the moment
this backend can only compile simple methods (both leaf and non-leaf).
Most of the work on the assembler (assembler_arm64.cc) has been done.
Some work on the LIR generation layer (functions such as OpRegRegImm
& friends) is still necessary. The register allocator still needs to
be adapted to the A64 instruction set (it is mostly unchanged from
the arm backend). Offsets for helpers in gen_invoke.cc still need to
be changed to work on 64-bit.

Just create an ArmCodeGenerator for arm64, but currently no code will
be generated for arm64.
The method filter can:
1. Skip methods with unsupported prototype.
2. Skip methods with unsupported dalvik byte code.
3. Skip methods with invocation to unsupported prototype.
These are temporary codes and should be removed later. But with this
patch, it won't break anything when we merge partly implemented arm64
backend later.

The compiler driver is a single object delegating work to the compiler, rather
than passing it through to every Compiler call make it a member of Compiler so
that it maybe queried. This simplifies the Compiler API and makes the
relationship to CompilerDriver more explicit.
Remove reference arguments that contravene code style.

This patch forces FE/ME to treat x86_64 as x86 exactly.
The x86_64 logic will be revised later when assembly will be ready.

Separate declaration from definition in certain places to work-around issues
with clang.
Remove bogus lock annotation at definition in compilers.cc that is already
present at the declaration.
Remove duplicate definition of ClassReference.

Also run tests with the optimizing compiler enabled when
the file art/USE_OPTIMIZING_COMPILER is present.
