Reland r20974: Unify and simplify the FastCloneShallowArrayStub

- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

Guard against stack overflow in Runtime::StringReplaceOneCharWithString.

Unfortunately, this only triggers with "ulimit -s 1024" (or less), so we
cannot have an mjsunit test. The test that fails is
test/mjsunit/string-replace-one-char.js on x64.debug.
