Implement Optimizing's constant folding as a visitor.
Refactor the logic of art::HConstantFolding::Run into a new
visitor, art::HConstantFoldingVisitor.

Fuse long and FP compare & condition on ARM in Optimizing.
Also:
- Stylistic changes in corresponding parts on the x86 and
x86-64 code generators.
- Update and improve the documentation of
art::arm::Condition.

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: Add -Wunused
Until the global CFLAGS are fixed, add Wunused. Fix declarations
in the optimizing compiler.

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)

optimizing: NullCheck elimination
How it works:
- run a type analysis to propagate null information on instructions
- during the last instruction simplifier remove null checks for which
the input is known to be not null
The current type analysis is actually a nullability analysis but it will
be reused in follow up CLs to propagate type information: so it keeps
the more convenient name.

Move existing optimizations to it.

Minor object store optimizations.
- Avoid emitting write barrier when the value is null.
- Do not do a typecheck on an arraystore when storing something that
was loaded from the same array.

Add trivial register hints to the register allocator.
- Add hints for phis, same as first input, and expected registers.
- Make the if instruction accept non-condition instructions.

Optimize suspend checks in optimizing compiler.
- Remove the ones added during graph build (they were added
for the baseline code generator).
- Emit them at loop back edges after phi moves, so that the test
can directly jump to the loop header.
- Fix x86 and x86_64 suspend check by using cmpw instead of cmpl.
