Avoid adding HWrapReceiver during graph building.

This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

Previously there were two ways to actually use the StringAddStub
from Hydrogen:
- Either using HStringAdd (which implied NO_STRING_CHECK_IN_STUB

- or using HCallStub with CodeStub::StringAdd (which implied
NO_STRING_ADD_FLAGS and expected the arguments to be on the

The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include:
...
* Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions.
* The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization.
Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.

This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.

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.
