Note that this is just enough for simple function call examples to
generate working code.

A good portion of this patch is the extra functions that needed to be
implemented to support the test case. e.g. storeRegToStackSlot,
loadRegFromStackSlot, eliminateFrameIndex.

Depends on D128428 <https://reviews.llvm.org/D128428>
