Fix broken runtime SetStatsEnabled logic
Previously, Runtime::SetStatsEnabled wouldn't take stats_enabled_
into account when deciding whether or not to increment / decrement
teh stats enabled counter. This resulted in counter underflows and
other errors which caused some CTS tests to fail.
Also added some locking to prevent race conditions.

Avoid some unnecessary use of stl types.
May be a minor performance win but really done for libc++ as this removes a
dependency on a library function whose prototype includes a std::string.

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.

Make debugger / jdwp compaction safe.
Fixed GetInstances, GetReferringObjects, CountInstances to use
VisitObjects instead of the live bitmap.
We now treat the object registry as system weaks and update the
objects when/if they move. Also added the recent_allocation_records_
as roots.

Move SwapBitmaps to ContinuousMemMapAllocSpace.
Moved the SwapBitmaps function to ContinuousMemMapAllocSpace since
the zygote space uses this function during full GC.
Fixed a place where we were casting a ZygoteSpace to a MallocSpace,
somehow this didn't cause any issues in non-debug builds.
Moved the CollectGarbage in PreZygoteFork before the lock to prevent
an occasional lock level violation caused by attempting to enqueue
java lang references with the a lock.

Thread local bump pointer allocator.
Added a thread local allocator to the heap, each thread has three
pointers which specify the thread local buffer: start, cur, and
end. When the remaining space in the thread local buffer isn't large
enough for the allocation, the allocator allocates a new thread
local buffer using the bump pointer allocator.
The bump pointer space had to be modified to accomodate thread
local buffers. These buffers are called "blocks", where a block
is a buffer which contains a set of adjacent objects. Blocks
aren't necessarily full and may have wasted memory towards the
end. Blocks have an 8 byte header which specifies their size and is
required for traversing bump pointer spaces.
Memory usage is in between full bump pointer and ROSAlloc since
madvised memory limits wasted ram to an average of 1/2 page per
block.
Added a runtime option -XX:UseTLAB which specifies whether or
not to use the thread local allocator. Its a NOP if the garbage
collector is not the semispace collector.
TODO: Smarter block accounting to prevent us reading objects until
we either hit the end of the block or GetClass() == null which
signifies that the block isn't 100% full. This would provide a
slight speedup to BumpPointerSpace::Walk.

Don't scan image space when starting runtime.
Bug 10432288.
Find Classes and Strings from dex caches lazily rather than when the image is
loaded.
Make class status changes do notifies when there can be waiters.
For Class lookup there's a pathology if we always search dex caches and
so after 1000 failures move all classes into the class table.
Be consistent in using "const char*" for class linker descriptors as this
most easily agrees with the type in the dex file.
Improve the intern run-test so that it has a case of a literal contained in the
image.
Modify image_test to allow any valid lock word rather than expecting 0, ideally
we wouldn't see inflated monitors but we do due to NotifyAll (see bug 6961405).

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.
