Clean up art::HConstant predicates.
- Make the difference between arithmetic zero and zero-bit
pattern non ambiguous.
- Introduce Boolean predicates in art::HIntConstant for when
they are used as Booleans.
- Introduce aritmetic positive and negative zero predicates
for floating-point constants.

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

Simplify unsigned comparisons against zero (with unit tests).
Rationale: Such cases occurs a lot after dynamic
bound check optimization (where the lower bound
is test against upper bound). Removing this
unnecessary test improves quality of code.

[optimizing] Fold HTypeConversion of constants
While looking into optimizing long shifts on x86, I found that the
compiler wasn't folding HTypeConversion of constants. Add simple
conversions of constants, taking care of float/double values
with NaNs and small/large values, ensuring Java conversion semantics.
Add checker cases to see that constant folding of HTypeConversion is
done.
Ensure 422-type-conversion type conversion routiness don't get
inlined to avoid compile time folding.

Simplify floating-point comparisons with NaN in Optimizing.
This change was suggested by Ian.
Also, simplify some art::HFloatConstant and
art::HDoubleConstant methods.

ART: Force constants into the entry block
Optimizations such as GVN and BCE make the assumption that all
constants are located in the entry block of the CFG, but not all
passes adhere to this rule.
This patch makes constructors of constants private and only accessible
to friend classes - HGraph for int/long constants and SsaBuilder for
float/double - which ensure that they are placed correctly and not
duplicated.
Note that the ArenaAllocatorAdapter was modified to not increment
the ArenaAllocator's internal reference counter in order to allow
for use of ArenaSafeMap inside an arena-allocated objects. Because
their destructor is not called, the counter does not get decremented.

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.
