Upgrade the old mangling from a list of argument types to a list of requiremnets. For now, only same-type requirements may actually be mangled since those are all that are available to the surface language. Reconstruction of existential types now consists of demangling (a list of) base protocol(s), decoding the constraints, and converting the same-type constraints back into a list of arguments. rdar://96088707
