  [Mem2Reg] Check that load type matches alloca type

Alloca promotion can only deal with cases where the load/store
types match the alloca type (it explicitly does not support
bitcasted load/stores).

With opaque pointers this is no longer enforced through the pointer
type, so add an explicit check.
