AArch64: Clean up CalleeSaveMethod frame and the use of temp registers.
CalleeSaveMethod frame size changes :
SaveAll : 368 -> 176
RefOnly : 176 -> 96
RefsAndArgs : 304 -> 224
JNI register spill size changes :
160 -> 88
In the transition assembly, use registers following the rules:
1. x0-x7 as temp/argument registers.
2. IP0, IP1 as scratch registers.
3. After correct type of callee-save-frame has been setup, all registers
are scratch-able(probably except xSELF and xSUSPEND).
4. When restore callee-save-frame, IP0 and IP1 should be untouched.
5. From C to managed code, we assume all callee save register in AAPCS
will be restored by managed code except x19(SUSPEND).
In quick compiler:
1. Use IP0, IP1 as scratch register.
2. Use IP1 as hidden argument register(IP0 will be scratched by
trampoline.)

AArch64: Jni compiler fixes
This patch fixes some of the issues with the ARM64 assembler and JNI
compiler.
The JNI compiler is not enabled by default, yet. To enable, change
line 1884 in compiler/driver/compiler_driver.cc, removing kArm64 from
the GenericJNI list.
The compiler passes all tests in jni_compiler_test.
Also change the common_compiler_test instruction-set-features logic.
We allow tests when the build-time features are a subset of the
runtime features.
Dex2oat cross-compiling is now working. A 32b version of dex2oat should
be able to compile correctly.

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.

AArch64: Add ARM64 Assembler
This patch adds the ARM64 Assembler and ManagedRegister backend.
The implementation of the Arm64Assembler class is based on VIXL (a
programmatic A64 Assembler - see external/vixl ).
