Load app images
Support in-place patching of the app image based on boot image
location and app oat location. Only loads for art run test so far
since we do not automatically generate app images for app installs.
N5 maps launch time (~200 runs):
Before: 930ms
After: 878.18ms
After + image class table: 864.57ms
TODO:
Oatdump support.
Store class loaders as class roots in image.

Move to newer clang annotations
Also enable -Wthread-safety-negative.
Changes:
Switch to capabilities and negative capabilities.
Future work:
Use capabilities to implement uninterruptible annotations to work
with AssertNoThreadSuspension.

Enable annotalysis on clang ART builds.
Fix clang build errors aswell as restructure locking/mutex code for correct
thread safety analysis support.
Reorder make dependencies so that host builds build first as they should
provide better compilation errors than target.
Remove host's use of -fno-omit-frame-pointer as it has no value with correct
use of CFI, which we should have.

Improve heap verification.
Re-enabled checking the allocation stack for heap verification.
Added tracking of recent frees in DlMallocSpace if debug spaces is
enabled. This is useful when you have heap corruption caused by a
live object referencing a recently freed object.
Added various other sanity checks in the GC.

More parallel GC, rewritten parallel mark stack processing.
Card scanning may now be done in parallel. This speeds up sticky and
reduces pause times for all GC types.
Speedup on my mako (ritz perf):
Average pause time for sticky GC (~250 samples):
Without parallel cards scanning enabled: 2.524904215ms
Parallel card scanning (num_gc_threads_): 1.552123552ms
Throughput (~250 samples):
Sticky GC throughput with parallel card scanning: 69MB/s
Sticky GC throughput without parallel card scanning: 51MB/s
Rewrote the mark stack processing to be LIFO and use a prefetch queue
like the non parallel version.
Cleaned up some of the logcat printing for the activity manager
process state listening.
Added unlikely hints to object scanning since arrays and classes are
scanned much less often than normal objects.
Fixed a bug where the number of GC threads was clamped to 1 due to a
bool instead of a size_t.
Fixed a race condition when we added references to the reference
queues. Sharded the reference queue lock into one lock for each reference
type (weak, soft, phatom, finalizer).
Changed timing splits to be different for processing gray objects with
and without mutators paused since sticky GC does both.
Mask out the class bit when visiting fields as an optimization, this is
valid since classes are held live by the class linker.
Partially completed: Parallel recursive mark + finger.

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.
