Hydrogen array constructor cleanup and improvements
...
* Cleanup of LCallNewArray::PrintDataTo() method
* Created HCallNewArray::PrintDataTo()
* Created many more tests in array-constructor-feedback.js
* Removed redundant instructions in
GenerateRecordCallTarget
* Bugfix in CreateArrayDispatchOneArgument: on a call to
new Array(0), we'd like to set the type feedback cell to
a packed elements kind, but we shouldn't do it if the
cell contains the megamorphic sentinel.
* When used from crankshaft, ArrayConstructorStubs can
avoid verifying that the function being called is the
array function from the current native context, relying
instead on the fact that crankshaft issues an
HCheckFunction to protect the constructor call. (this
new minor key is used in LCodeGen::DoCallNewArray(), and
influences code generation in
CodeStubGraphBuilderBase::BuildArrayConstructor()).
* Optimization: the array constructor specialized for
FAST_SMI_ELEMENTS can save some instructions by looking
up the correct map on the passed in constructor, rather
than indexing into the array of cached maps per element
kind.

Refactor Hydrogen environment liveness analysis into an HPhase.
...
Rename EnvironmentSlotLivenessAnalyzer to HEnvironmentLivenessAnalysisPhase,
following naming scheme suggested by danno@chromium.org in

The environment slot liveness analysis now uses the phase zone for
all its allocations.
