ART: clear dirty cards of alloc space for MS/CMS partial and full GCs For MS/CMS partial and full GCs, we could clear the dirty cards of alloc space when we process cards as we care about the dirty cards after GC starts.

Compatibility layer to transition from UniquePtr to std::unique_ptr. Use ART_WITH_STLPORT (enabled for the target) to cause the use of UniquePtr, for the host switch to std::unique_ptr. For now the type remains called UniquePtr. Make dalvik compile with clang on the host, move its build to C++11. Change-Id: I5ba8d2757904bc089ed62047ea03de3c0853fb12

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. Change-Id: I72cea8da9a3757b1a0b3acb4081feccb7c6cef90

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. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
