x86/x86-64 read barrier support for concurrent GC in Optimizing.
This first implementation uses slow paths to instrument heap
reference loads and GC root loads for the concurrent copying
collector, respectively calling the artReadBarrierSlow and
artReadBarrierForRootSlow (new) runtime entry points.
Notes:
- This implementation does not instrument HInvokeVirtual
nor HInvokeInterface instructions (for class reference
loads), as the corresponding read barriers are not stricly
required with the current concurrent copying collector.
- Intrinsics which may eventually call (on slow path) are
disabled when read barriers are enabled, as the current
slow path infrastructure does not support this case.
- When read barriers are enabled, the code generated for a
HArraySet instruction always go into the array set slow
path for object arrays (delegating the operation to the
runtime), as we are lacking a mechanism to keep a
temporary register live accross a runtime call (needed for
the instrumentation of type checking code, which requires
two successive read barriers).

ARM: Use hardfp calling convention between java to java call.
This patch default to use hardfp calling convention. Softfp can be enabled

We get about -1 ~ +5% performance improvement with different benchmark
tests. Hopefully, we should be able to get more performance by address the left
TODOs, as some part of the code takes the original assumption which is not
optimal.
DONE:
1. Interpreter to quick code
2. Quick code to interpreter
3. Transition assembly and callee-saves
4. Trampoline(generic jni, resolution, invoke with access check and etc.)
5. Pass fp arg reg following aapcs(gpr and stack do not follow aapcs)
6. Quick helper assembly routines to handle ABI differences
7. Quick code method entry
8. Quick code method invocation
9. JNI compiler
TODO:
10. Rework ArgMap, FlushIn, GenDalvikArgs and affected common code.

Add mark compact collector.
The mark compact collector is a 4 phase collection, doing a normal
full mark_sweep, calculating forwarding addresses of objects in the
from space, updating references of objects in the from space, and
moving the objects in the from space.
Support is diabled by default since it needs to have non movable
classes and field arrays. Performance numbers is around 50% as fast.
The main advantage that this has over semispace is that the worst
case memory usage is 50% since we only need one space isntead of two.
TODO: Make field arrays and classes movable. This causes complication
since Object::VisitReferences relies on these, so if we update the
fields of an object but another future object uses this object to
figure out what fields are reference fields it doesn't work.

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.

Use direct class pointers at allocation sites in the compiled code.
- Rather than looking up a class from its type ID (and checking if
it's resolved/initialized, resolving/initializing if not), use
direct class pointers, if possible (boot-code-to-boot-class pointers
and app-code-to-boot-class pointers.)
- This results in a 1-2% speedup in Ritz MemAllocTest on Nexus 4.
- Embedding the object size (along with class pointers) caused a 1-2%
slowdown in MemAllocTest and isn't implemented in this change.
- TODO: do the same for array allocations.

app-code-to-app-class pointers.

Fixed a bug where we didn't set the concurrent start bytes after
switching the allocator from bump pointer to ROSAlloc in the
zygote. This caused excessive memory usage.
Added the method verifiers as roots to fix an issue caused by
RegTypes holding a Class*.

Compact zygote.
We now start out using the bump pointer allocator and switch to
the free list collector (ROSAlloc) after the zygote forks.
Before compaction:
Zygote size: 9060352
After compaction
Zygote size: 8425864
The main reason the size doesn't reduce more is that most of the
zygote space is non-movable objects allocated by
VMRuntime.newNonMovableObject. The objects which are non-movable
but could be movable include around 10000 classes and some number
of fields and methods.

Compacting collector.
The compacting collector is currently similar to semispace. It works by
copying objects back and forth between two bump pointer spaces. There
are types of objects which are "non-movable" due to current runtime
limitations. These are Classes, Methods, and Fields.
Bump pointer spaces are a new type of continuous alloc space which have
no lock in the allocation code path. When you allocate from these it uses
atomic operations to increase an index. Traversing the objects in the bump
pointer space relies on Object::SizeOf matching the allocated size exactly.
Runtime changes:
JNI::GetArrayElements returns copies objects if you attempt to get the
backing data of a movable array. For GetArrayElementsCritical, we return
direct backing storage for any types of arrays, but temporarily disable
the GC until the critical region is completed.
Added a new runtime call called VisitObjects, this is used in place of
the old pattern which was flushing the allocation stack and walking
the bitmaps.
Changed image writer to be compaction safe and use object monitor word
for forwarding addresses.
Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc..
TODO: Enable switching allocators, compacting on background, etc..

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
