Move mirror::ArtMethod to native
Optimizing + quick tests are passing, devices boot.
TODO: Test and fix bugs in mips64.
Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS.
Some of the savings are from removal of virtual methods and direct
methods object arrays.

Fixed optimizing compiler bug where we used a normal stack location
instead of double on ARM64, this fixes the debuggable tests.

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.)

AArch64: Addressing Cortex-A53 erratum 835769.
Some early revisions of the Cortex-A53 have an erratum (835769) whereby
it is possible for a 64-bit multiply-accumulate instruction in AArch64
state to generate an incorrect result. The conditions which a portion
of code must satisfy in order for the issue to be observed are somewhat
complex, but all cases end with a memory (load, store, or prefetch)
instruction followed immediately by the multiply-accumulate operation.
This commit makes sure to insert a nop instruction before a 64-bit msub
instruction, whenever the latter is preceded by a memory instruction.
This behaviour should make it impossible for the Arm64 backend to
generate a sequence of instructions which matches the erratum
conditions.

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.)

Replace memory barriers to better reflect Java needs.
Replaces barriers that enforce ordering of one access type
(e.g. Load) with respect to another (e.g. store) with more general
ones that better reflect both Java requirements and actual hardware
barrier/fence instructions. The old code was inconsistent and
unclear about which barriers implied which others. Sometimes
multiple barriers were generated and then eliminated;
sometimes it was assumed that certain barriers implied others.
The new barriers closely parallel those in C++11, though, for now,
we use something closer to the old naming.

OpRegRegImm will fall back to loading a constant into a register

example, the case when we allocate large stack frames. However,
the currently chosen operations are add/sub shifted, which does
*not* allow to specify SP (x31 will be interpreted as xzr). Switch
to add/sub extended. There won't be a practical difference, as we
do not call with anything other than 0 shift.

64-bit temp register support.
Add a 64-bit temp register allocation path. The recent physical
register handling rework supports multiple views of the same
physical register (or, such as for Arm's float/double regs,
different parts of the same physical register).
This CL adds a 64-bit core register view for 64-bit targets. In
short, each core register will have a 64-bit name, and a 32-bit
name. The different views will be kept in separate register pools,
but aliasing will be tracked. The core temp register allocation
routines will be largely identical - except for 32-bit targets,
which will continue to use pairs of 32-bit core registers for holding
long values.

AArch64: Change arm64 backend to produce A64 code.
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.

AArch64: Added arm64 quick backend as an arm clone.
Created a new directory arm64 under compiler/dex/quick which contains
a copy of the 32-bit arm backend. In following CLs, this code will
be replaced/modified to support Aarch64.
