Optimizing: Tag Arena allocations with their source.
This adds the ability to track where we allocate memory
when the kArenaAllocatorCountAllocations flag is turned on.
Also move some allocations from native heap to the Arena
and remove some unnecessary utilities.

Improved side effect analysis (field/array write/read).
Rationale:
Types (int, float etc.) and access type (field vs. array)
can be used to disambiguate write/read side-effects analysis.
This directly improves e.g. dead code elimination and licm.

ART: Run GraphChecker after Builder and SsaBuilder
This patch refactors the way GraphChecker is invoked, utilizing the
same scoping mechanism as pass timing and graph visualizer. Therefore,
GraphChecker will now run not just after instances of HOptimization
but after the builders and reg alloc, too.

Optimizing: Move optimization objects to Arena.
This should reduce the stack size needed by the
OptimizingCompiler::CompileOptimized() which was very
close to our limits for clang builds, causing repeated
build breakages on otherwise healthy changes:
art/compiler/optimizing/optimizing_compiler.cc:395:37:
error: stack frame size of 1760 bytes in function
'art::OptimizingCompiler::CompileOptimized'
[-Werror,-Wframe-larger-than=]

ART: Dead block removal
Adds a new pass which finds all unreachable blocks, typically due to
simplifying an if-condition to a constant, and removes them from the
graph. The patch also slightly generalizes the graph-transforming
operations.

ART: Add -Wunused
Until the global CFLAGS are fixed, add Wunused. Fix declarations

Reference type propagation
- propagate reference types between instructions
- remove checked casts when possible
- add StackHandleScopeCollection to manage an arbitrary number of stack
handles (see comments)

Create HGraph outside Builder, print timings
This patch refactors the way HGraph objects are created, moving the
instantiation out of the Builder class and creating the CodeGenerator
earlier. The patch uses this to build a single interface for printing
timings info and dumping the CFG.

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.
