Michael Stanton 3d58b82add Fix for 435073: CHECK failure in CHECK(p->IsSmi()) failed.
The bug was an error when copying arrays in crankshaft. If it's a holey smi
array, the copy must be done as FAST_HOLEY_ELEMENTS to prevent representation
changes from being inserted that deopt on encountering the hole.

Also, prevent inlining array pop() and shift() if the length is read-only.
