Summary: Use the SP32 physical register as the base for FrameIndex lowering. Update it and the __stack_pointer global var in the prolog and epilog. Extend the mapping of virtual registers to wasm locals to include the physical registers. Rather than modify the target-independent PrologEpilogInserter (which asserts that there are no virtual registers left) include a slightly-modified copy for Wasm that does not have this assertion and only clears the virtual registers if scavenging was needed (which of course it isn't for wasm).
