Remove object_utils.h.
Break into object_lock, field_helper and method_helper.
Clean up header files following this.
Also tidy some of the Handle code in response to compiler errors when resolving
the changes in this CL.

Ensure classes are initialized rather than initializing.
A class can be being initialized on a different thread, in that case other
threads should block trying to access the class. The initializing state shows
the class is being initialized but not that its safe for other threads to
access. Change occurances of IsInitializing to IsInitialized primarily in
slow-path code.

Fix an outstanding compaction bug in interpreter.
Fixed a bug in DoFieldPut where the FieldHelper GetType could cause
thread suspension which would result in a stale obj.
Added more handles in the class linker to facilitate moving fiels
and methods in the future.
Removed un-necessarly passing handle references since these are value
types and don't need to be passed by reference.
Added a special NullHandle type which allows null handles without a
handle scope.

Add Handle/HandleScope and delete SirtRef.
Delete SirtRef and replaced it with Handle. Handles are value types
which wrap around StackReference*.
Renamed StackIndirectReferenceTable to HandleScope.
Added a scoped handle wrapper which wraps around an Object** and
restores it in its destructor.
Renamed Handle::get -> Get.

Refactor reflective method invocation.
Move invocation code out of JNI internal into reflection, including ArgArray
code. Make reflective invocation use the ArgArray to build arguments rather
than allocating a jvalue[] and unboxing arguments into that.
Move reflection part of jni_internal_test into reflection_test.
Make greater use of fast JNI.

Work in the direction of hard float quick ABIs.
Pass a shorty to ArtMethod::Invoke so that register setup can use it.
Document x86-64 ABI.
Add extra debug output for one JNI native method registration fails, namely a
dump of the Class and its dex file's location.
Add hack to get testing of OatMethod's without GC maps working in 64bit.

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.

Enable moving classes.
Slight reduction in Zygote size, memory savings are in the noise.
Before: Zygote size: 8739224
After: Zygote size: 8733568
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*.
Added logic to clear card table in the SemiSpace collector, this
reduces DalvikOther from ~2400k -> ~1760k when using the SemiSpace
collector.
Added a missing lock to the timing loggers which caused a rare
one time crash in std::set.

Add missing push/pop shadow frame to artInterpreterToCompiledCodeBridge.
EnsureInitialized can cause GC to occur. Since the shadow frame wasn't
being pushed it meant that the references inside wouldn't get updated
by the moving garbage collector.

Cleanup invoke in interpreter.
Some cleanup in invocation stuff:
- Get the number of invoke arguments from instruction (vA) rather than get it
from its code item. This benefits to native invoke since we no longer need to
parse the method's shorty. Also pass the low 16 bits of instructions to avoid
fetching it twice when reading vA.
- Remove "is_static" tests by taking advantage of invoke type template argument
rather than testing method's access flags.
- Ensure Instruction::GetArgs is inlined.
- Check exception when initializing method's class when transitioning from
interpreter to compiled code (artInterpreterToCompiledCodeBridge).
- Move UnstartedRuntimeInvoke function to interpreter_common.cc and make it
static as it's only used by DoInvoke and DoInvokeVirtualQuick functions.
- Avoid duplicating code in ShadowFrame::Create.
Performance remains the same according to benchmarks. Hopefully, this should be
addressed in next CLs, especially by improving new shadow frame initialization.

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.
