dex2oat: Pack likely-dirty objects together when generating the boot image
This introduces a new algorithm into image writer which "bins" objects
by how likely they are to be dirtied at runtime. Objects in the same bin
are placed contiguously in memory (i.e. into the same page). We try to
tune the bin selection based on how clean or how dirty the object will
likely be at runtime.
As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in
zygote (shared-dirty).
There is still about 800KB of objects that are clean but located in
dirty pages, so with more analysis we can tune the bin selection and get
even more memory savings.

Optimize get/set reflection performance
Speedups mostly from reducing how often access checks are needed,
and adding more inlining, and adding templates.

More advanced timing loggers.
The new timing loggers have lower overhead since they only push into
a vector. The new format has two types, a start timing and a stop
timing. You can thing of these as brackets associated with a
timestamp. It uses these to construct various statistics when needed,
such as: Total time, exclusive time, and nesting depth.
Changed PrettyDuration to have a default of 3 digits after the decimal
point.
Exaple of a GC dump with exclusive / total times and indenting:

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.

- GetDalvikCacheOrDie now requires a mandatory subdirectory argument,

Avoid std::string allocations for finding an array class.
Introduce ClassLinker::FindArrayClass which performs an array class lookup
given the element/component class. This has a 16 element cache of recently
looked up arrays.
Pass the current thread to ClassLinker Find .. Class routines to avoid calls
to Thread::Current().
Avoid some uses of FindClass in the debugger where WellKnownClasses is a
faster and more compacting GC friendly alternative.

Create CompilerOptions
Package up most compiler related options in CompilerOptions. Details include:
- Includes compiler filter, method thresholds, SEA IR mode.
- Excludes those needed during Runtime::Init such as CompilerCallbacks and VerificationResults.
- Pass CompilerOptions to CompilerDriver.
- Remove CompilerOptions from Runtime.
- Add ability to pass options for app and image dex2oat to runtime via
-Xcompiler-option and -Ximage-compiler-option respectively.
Other
- Replace 2x CompilerCallbacks implementations with one.
- Factor out execv code for use by both image and oat generation.
- More OatFile error_msg reporting.
- DCHECK for SuspendAll found trying to run valgrind.

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.
