Remove unused DMB code paths in the ARM64 Optimizing Compiler
Currently all ARM64 CPUs will be using the acquire-release code paths.
This patch removes the instruction set feature PreferAcquireRelease()
as well as all the unused DMB code paths.

Opt Compiler: ARM64 goodness
This patch:
* Switches on PreferAcquireRelease() (used to decide if load/store
volatile should use acquire release-semantics or explicit memory
barriers). Note that for ARMv8 CPUs we should always prefer this
(as proved by synthetic benchmarks on A53, A57 and Denver).
* Enables the use of constants for HBoundsCheck

Fixed layout for dex caches in boot image.
Define a fixed layout for dex cache arrays (type, method,
string and field arrays) for dex caches in the boot image.
This gives those arrays fixed offsets from the boot image
code and allows PC-relative addressing of their elements.
Use the PC-relative load on arm64 for relevant instructions,
i.e. invoke-static, invoke-direct, const-string,
const-class, check-cast and instance-of. This reduces the
arm64 boot.oat on Nexus 9 by 1.1MiB.
This CL provides the infrastructure and shows on the arm64
the gains that we can achieve by having fixed dex cache
arrays' layout. To fully use this for the boot images, we
need to implement the PC-relative addressing for other
architectures. To achieve similar gains for apps, we need
to move the dex cache arrays to a .bss section of the oat
file. These changes will be implemented in subsequent CLs.
(Also remove some compiler_driver.h dependencies to reduce
incremental build times.)

Opt Compiler: ARM64: Enable explicit memory barriers over acquire/release
Implement remaining explicit memory barrier code paths and temporarily
enable the use of explicit memory barriers for testing.
This CL also enables the use of instruction set features in the ARM64
backend. kUseAcquireRelease has been replaced with PreferAcquireRelease(),
which for now is statically set to false (prefer explicit memory barriers).
Please note that we still prefer acquire-release for the ARM64 Optimizing
Compiler, but we would like to exercise the explicit memory barrier code
path too.

Instruction set features for ARM64, MIPS and X86.
Also, refactor how feature strings are handled so they are additive or
subtractive.
Make MIPS have features for FPU 32-bit and MIPS v2. Use in the quick compiler
rather than #ifdefs that wouldn't have worked in cross-compilation.
Add SIMD features for x86/x86-64 proposed in:
