Rosalloc thread local allocation path without a cas.
Speedup on N4:
MemAllocTest 3044 -> 2396 (~21% reduction)
BinaryTrees 4101 -> 2929 (~26% reduction)

ART: Wrap AllocThreadUnsafe in Valgrind wrapper
This needs to be wrapped as it is being used during compaction.

ART: Fix valgrind
Allow ValgrindMallocSpace wrapper for RosAlloc.Requires refactoring,
as ValgrindMallocSpace was bound to the signature of DlMallocSpace.
Also turn of native stack dumping when running under Valgrind to
work around b/18119146.

Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.
Fix associated errors about unused paramenters and implict sign conversions.
For sign conversion this was largely in the area of enums, so add ostream
operators for the effected enums and fix tools/generate-operator-out.py.
Tidy arena allocation code and arena allocated data types, rather than fixing
new and delete operators.
Remove dead code.

Clean-up heap spaces.
We now use the CMS collector instead of the semispace collector when
the phone is booting. We still perform compaction during the zygote
space creation. This reduces time spent in GC by ~2s during boot
and doesn't affect zygote space size.
Changed the space creation logic to create the temp space when a
background transition occurs.
Added a flag to each space which is true if you are allowed to
move objects that are within this space.
Removed SwapSemiSpaces call from the semi space collector, it is now
the job of the caller to do this with threads suspended. This
simplifies the logic in the zygote compaction / heap transition code
since these do not copy from one semispace to another.
Added Space::Clear to RosAllocSpace and DlMallocSpace. This greatly
simplifies the code used for collector transitions.
Time spent in GC creating zygote space:
Before: 3.4s, After: 1.28s
No change in zygote space size.

Fix valgrind gtests and memory leaks.
All tests pass other than image_test which passes if some bad reads
are disabled (buzbee working on this).

Make allocations report usable size.
Work-in-progress to allow arrays to fill usable size. Bug: 13028925.
Use C++11's override keyword on GCC >= 2.7 to ensure that we override GC and
allocator methods.
Move initial mirror::Class set up into a Functor so that all allocated objects
have non-zero sizes. Use this property to assert that all objects are never
larger than their usable size.
Other bits of GC related clean-up, missing initialization, missing use of
const, hot methods in .cc files, "unimplemented" functions that fail at
runtime in header files, reducing header file includes, move valgrind's space
into its own files, reduce number of array allocation routines.
