Remove the IsLoadable flag from SILType, and the isInvalid() state for SILType. This frees up an extra bit in SILType, which we can expose to LLVM through PointerLikeTypeTraits. Use this bit in a PointerUnion, which allows simplifying ValueBase, which happened to be the last use of the isInvalid() state. Swift SVN r5218
