Refactored optimization passes setup.
Rationale:
Refactors the way we set up optimization passes
in the compiler into a more centralized approach.
The refactoring also found some "holes" in the
existing mechanism (missing string lookup in
the debugging mechanism, or inablity to set
alternative name for optimizations that may repeat).

optimizing: Refactor statistics to use OptimizingCompilerStats helper
Remove all copies of 'MaybeRecordStat', replacing them with a single
OptimizingCompilerStats::MaybeRecordStat helper.

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.

load store elimination.
This adds a pass to eliminate some unnecessary heap loads/stores. It
first collects heap locations and then tracks values stored to those heap
locations. Alias analysis is done based on offset, type, singleton,
pre-existence, etc.
