ART: Add templated VisitObjects
Add templated versions of VisitObjects that accept visitors. This
allows to use more modern lambdas.
Test: m

Replace ObjectSet with LargeObjectBitmap.
Speeds up large object marking since large objects no longer required
a lock. Changed the GCs to use the heap bitmap for marking objects
which aren't in the fast path. This eliminates the need for a
MarkLargeObject function.
Maps before (10 GC iterations):
Mean partial time: 180ms
Mean sticky time: 151ms
Maps after:
Mean partial time: 161ms
Mean sticky time: 101ms
Note: the GC durations are long due to recent ergonomic changes and
because the fast bulk free hasn't yet been enabled. Over 50% of the
GC time is spent in RosAllocSpace::FreeList.

Refactor space bitmap to support different alignments.
Required for:
Using space bitmaps instead of std::set in mod union table +
remembered set.
Using a bitmap instead of set for large object marking.

Refactor some GC code.
Reduced amount of code in mark sweep / semi space by moving
common logic to garbage_collector.cc. Cleaned up mod union tables
and deleted an unused implementation.

Fix up TODO: c++0x, update cpplint.
Needed to update cpplint to handle const auto.
Fixed a few cpplint errors that were being missed before.
Replaced most of the TODO c++0x with ranged based loops. Loops which
do not have a descriptive container name have a concrete type instead
of auto.

Disable and remove finger.
Finger is useless for multithreaded GC, removing it should provide a
slight speed up due to avoided comparison.

GC data structures allocation tracking
Adds a new stl compatible allocator that is used in most GC data
structures. When the data structures allocate and free memory, it
lets the heap know of how much memory was allocated or freed. Using
this info, we dump the approximated stl data structures memory usage
when a sigquit occurs.
The allocation tracking can be disabled with a compile time boolean
flag to remove performance impact.

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.
