Tidy RegStorage for X86.
Don't use global variables initialized in constructors to hold onto constant

of lookup tables. Elsewhere prefer to use constexpr values as they will have

ART: Rework quick entrypoint code in Mir2Lir, cleanup
To reduce the complexity of calling trampolines in generic code,
introduce an enumeration for entrypoints. Introduce a header that lists
the entrypoint enum and exposes a templatized method that translates an
enum value to the corresponding thread offset value.
Call helpers are rewritten to have an enum parameter instead of the
thread offset. Also rewrite LoadHelper and GenConversionCall this way.
It is now LoadHelper's duty to select the right thread offset size.
Introduce InvokeTrampoline virtual method to Mir2Lir. This allows to
further simplify the call helpers, as well as make OpThreadMem specific
to X86 only (removed from Mir2Lir).
Make GenInlinedCharAt virtual, move a copy to X86 backend, and simplify
both copies. Remove LoadBaseIndexedDisp and OpRegMem from Mir2Lir, as they
are now specific to X86 only.
Remove StoreBaseIndexedDisp from Mir2Lir, as it was only ever used in the
X86 backend.
Remove OpTlsCmp from Mir2Lir, as it was only ever used in the X86 backend.
Remove OpLea from Mir2Lir, as it was only ever defined in the X86 backend.
Remove GenImmedCheck from Mir2Lir as it was neither used nor implemented.

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.

Register promotion support for 64-bit targets
Not sufficiently tested for 64-bit targets, but should be
fairly close.
A significant amount of refactoring could stil be done, (in
later CLs).
With this change we are not making any changes to the vmap
scheme. As a result, it is a requirement that if a vreg
is promoted to both a 32-bit view and the low half of a
64-bit view it must share the same physical register. We
may change this restriction later on to allow for more flexibility
for 32-bit Arm.
For example, if v4, v5, v4/v5 and v5/v6 are all hot enough to
promote, we'd end up with something like:
v4 (as an int) -> r10
v4/v5 (as a long) -> r10
v5 (as an int) -> r11
v5/v6 (as a long) -> r11
Fix a couple of ARM64 bugs on the way...

OpRegRegImm will fall back to loading a constant into a register
and then doing the operation with three registers. That is, for
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.

Arm64 hard-float
Basic enabling of hard-float for Arm64. In future CLs we'll
consolidate the various targets - there is a lot of overlap.
Compilation remains turned off in this CL, but I expect
to enable a subset shortly. With compilation fully enabled
(including the EXPERIMENTAL opcodes with the exception of
REM and THROW), we get the following run-test results:
003-omnibus-opcode failures:
Classes.checkCast
Classes.arrayInstance
UnresTest2
Haven't gone deep, but these appear to be related to throw/catch and/or
stacktrace.
For REM, the generated code looks reasonable to me - my guess is that
we've got something wrong on the transition to the runtime. Haven't
looked deeper yet, though.
The bulk of the other failure also appear to be related to transitioning
to the runtime system, or handling try/catch.

AArch64: fixing some assertions.
Fixing some assertions while attempting to get libartd.so to work.
Fixing also the shift logic in LoadBaseIndexed() and StoreBaseIndexed().
This commit only fixes a part of the assertion issues.

AArch64: Enable LONG_* and INT_* opcodes.
This patch fixes some of the issues with LONG and INT opcodes. The patch
has been tested and passes all the dalvik tests except for 018 and 107.

AArch64: fixes in A64 code generation.
- Disabled special method compilation, as it requires hard-float ABI,
- Disabled suspend checks, as runtime is not yet ready (e.g. trampolines
are not setting the suspend register, etc),
- Changing definition of zero register (the zero register has now 0x3f
as its register number),
- Fixing some issues with handling of cmp instructions in the assembler:
we now use the shift-register rather than the extended-register variant
of cmp and cmn,
- Partially fixing register setup (register sN is now mapped to dN),
- Fixing and completing implementation of register spills/unspills,
- Fixing LoadBaseDispBody() and StoreBaseDispBody().

ART: Add more ThreadOffset in Mir2Lir and backends
This duplicates all methods with ThreadOffset parameters, so that
both ThreadOffset<4> and ThreadOffset<8> can be handled. Dynamic
checks against the compilation unit's instruction set determine
which pointer size to use and therefore which methods to call.
Methods with unsupported pointer sizes should fatally fail, as
this indicates an issue during method selection.

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.

Cleanup ARM load/store wide and remove unused param s_reg.
Use a single LDRD/VLDR instruction for wide load/store on
ARM, adjust the base pointer if needed. Remove unused
parameter s_reg from LoadBaseDisp(), LoadBaseIndexedDisp()
and StoreBaseIndexedDisp() on all architectures.

Remove LoadBaseDispWide and StoreBaseDispWide.
Just pass k64 or kDouble to non-wide versions.

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.
