Array constructor shouldn't require a Cell, just an AllocationSite.
...
The Array constructor has a needless dependency on an input argument
that is a Cell. It uses this to walk through to an AllocationSite.
The dependency hampers future work. Instead, pass the AllocationSite
as input to the Array constructor.

Inline zero argument array constructor.

patch from issue 54583003 (dependent code).
Zero arguments - very easy
1 argument - three special cases:
a) If length is a constant in valid array length range,
no need to check it at runtime.
b) respect DoNotInline feedback on the AllocationSite for
cases that the argument is not a smi or is an integer
with a length that should create a dictionary.
c) if kind feedback is non-holey, and length is non-constant,
we'd have to generate a lot of code to be correct.
Don't inline this case.
N arguments - one special case:
a) If a deopt ever occurs because an input argument isn't
compatible with the elements kind, then set the
DoNotInline flag.

Inline number to string conversion for string addition into BinaryOp(Stub).
...
This fixes a performance regression that was caused by converting the
BinaryOpStub to a Hydrogen code stub. It also fixes a leftover TODO wrt.
the handling of Number*String or String*Number versions of the stub.

Extract hardcoded error strings into a single place and replace them with enum.
...
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.
Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:
It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.
From the other hand the developers have to add new strings into that enum.

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.

Fix invalid array length check in TransitionElementsKindStub.
...
The stub used to check the length of the JS array to see if
there's a need to duplicate the elements backing store. This
way it will not duplicate the elements array when going from
double to object even if the elements array is not the empty
fixed array. Later on it will then store pointers into a
FixedDoubleArray.
The native code stub used to check whether elements points to
the empty_fixed_array singleton instead of testing the length.
The Hydrogen stub does that as well now.

Generate StoreGlobal stubs with Hydrogen

- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.

The problem is the HCallConstantFunction which is not context sensitive, so we leak the builtin. We first need a Hydrogen version of __ IvokeBuiltin.

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.
