It had only 2 uses: One use could be rewritten in a simpler way, and the other
is actually more readable after inlining and fixing the comments.

Port r10356 (69da81).

Original commit message:
Loosen the requirement for Map equivalency on several map checks, including checks up the prototype chain, that are not sensitive to ElementsKinds. These selected map checks should also match against FAST_DOUBLE_ELEMENT and FAST_ELEMENT transitions of the original map. This specifically helps all variants of transitioned JSArrays to still efficiently call builtins like push, pop and sort.

Port r10374 (03bbe39).

Note: the MIPS version was not affected by the bug. This is merely a style cleanup.

Original commit message:
An off-by-one in the register allocator could lead to allocating (and
clobbering) the reserved 0.0 double register.  This required a function with
14 or more live double values.
