Implement in-heap backing store for typed arrays.
...
This adds a fixed array sub-type that will represent a backing store for
typed arrays allocated with TypedArray(length) construtor.

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.
