Change 64 bit ArtMethod fields to be pointer sized
Changed the 64 bit entrypoint and gc map fields in ArtMethod to be
pointer sized. This saves a large amount of memory on 32 bit systems.
Reduces ArtMethod size by 16 bytes on 32 bit.
Total number of ArtMethod on low memory mako: 169957
Image size: 49203 methods -> 787248 image size reduction.
Zygote space size: 1070 methods -> 17120 size reduction.
App methods: ~120k -> 2 MB savings.
Savings per app on low memory mako: 125K+ per app
(less active apps -> more image methods per app).
Savings depend on how often the shared methods are on dirty pages vs
shared.
TODO in another CL, delete gc map field from ArtMethod since we
should be able to get it from the Oat method header.

ART: Set default visibility to protected
Set default visibility of symbols to protected. This allows the
linker to optimize internal calls and helps avoid plt calls.
Make almost all assembly stubs hidden, as -fvisibility does not
seem to apply to them. Change the assembly tests accordingly. Also
allows to clean up previous hacks to avoid plt calls.

Make X86 assembly labels local.
Avoids the symbols being part of the symbol file and confusing tools like gdb.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.

Use macros to remove CFI information for MAC OS/X
Place allocation macros inline for x86 as the macros aren't/can't
go through the Linux/OSX normalizing macro wrappers.
Switch to clang for OS/X host build thereby enabling -std=gnu++11
and -Wthread-safety. Remove the -Wstrict-aliasing numeric option
as 3 is the default warning level and warning levels aren't
supported by clang's command line.
This builds as far as gtests which fail due to assumptions they
would only ever compile on non-GCC with RTTI.

Make x86 runtime PIC
The existing code in runtime/arch/x86 doesn't use PIC code to call
routines, and this causes a message that libart{,d}.so having text
relocations to be genartion. That message, in turn, messes up running
the art-target tests.

Get PORTABLE + SMALL on x86.
Implemented the portable resolution trampoline and
the portable to interpreter bridge.
Also work on integrating SEA_IR in the PORTABLE+SMALL framework.
Refactor some naming and correct indenting.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.
