Fix LSA hunt for original reference bug.
Fix a bug in LSA where it doesn't take IntermediateAddress
into account during hunting for original reference.
In following example, original reference i0 can be transformed
by NullCheck, BoundType, IntermediateAddress, etc.
i0 NewArray
i1 HInstruction(i0)
i2 ArrayGet(i1, index)

ART: Use ScopedArenaAllocator for pass-local data.
Passes using local ArenaAllocator were hiding their memory
usage from the allocation counting, making it difficult to
track down where memory was used. Using ScopedArenaAllocator
reveals the memory usage.
This changes the HGraph constructor which requires a lot of
changes in tests. Refactor these tests to limit the amount
of work needed the next time we change that constructor.

Test: Build with kArenaAllocatorCountAllocations = true.

ART: Introduce compiler data type.
Replace most uses of the runtime's Primitive in compiler
with a new class DataType. This prepares for introducing
new types, such as Uint8, that the runtime does not need
to know about.

Create load store analysis pass
This CL separates load store analysis from LSE pass.
The load and store analysis in LSE pass records information
about heap memory accesses for arrays and fields.
Such information can also be used in the other optimizations like
instruction scheduling pass which can eliminate side-effect
dependencies between memory accesses to different locations.
