Introduce a class to implement optimization passes.
- Add art::HOptimization.
- Rename art::ConstantPropagation to art::HConstantFolding in
compiler/optimizing/constant_folding.h to avoid name
clashes with a class of the same name in
compiler/dex/post_opt_passes.h.
- Rename art::DeadCodeElimination to
art::HDeadCodeElimination for consistency reasons.
- Have art::HDeadCodeElimination and art::HConstantFolding
derive from art::HOptimization.
- Start to use these optimizations in
art:OptimizingCompiler::TryCompile.
