The grow_memory and current_memory instructions are expected to be officially renamed to mem.grow and mem.size. Introduce new intrinsics with the new names. These new names aren't yet official, so for now, use them at your own risk. Also, take this opportunity to add arguments for the currently unused immediate field in those instructions. llvm-svn: 323222
