Global Value Numbering.
Implement the Global Value Numbering for optimization
purposes. Use it for the null check and range check
elimination as the LVN used to do.
The order of evaluation of basic blocks needs improving as
we currently fail to recognize some obviously identical
values in methods with more than one loop. (There are three
disabled tests that check this. This is just a missed
optimization, not a correctness issue.)

Improve tracking of memory locations in LVN.
Rewrite the tracking of values stored in memory to allow
recognizing the same value after storing it in memory and
loading it back to vreg. Drop reliance on value name
ordering for memory versioning in preparation for GVN.
Also fix a few minor issues in LVN.

Now we have a proper C++ library, use std::unique_ptr.
Also remove the Android.libcxx.mk and other bits of stlport compatibility
mechanics.

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.

Create a scoped arena allocator and use that for LVN.
This saves more than 0.5s of boot.oat compilation time
on Nexus 5.
TODO: Move other stuff to the scoped allocator. This CL
alone increases the peak memory allocation. By reusing
the memory for other parts of the compilation we should
reduce this overhead.

Fix and rewrite local value numbering.
Fix memory versioning to take aliasing and method calls
into account. Use more instructions for the null check
elimination. Return the local value name of the register
defined by the instruction if applicable.

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.
