; It's not legal to fold a load from 32-bit stack slot into a 64-bit
; instruction. If done, the instruction does a 64-bit load and that's not
; safe. This can happen we a subreg_to_reg 0 has been coalesced. One
; exception is when the instruction that folds the load is a move, then we
; can simply turn it into a 32-bit load from the stack slot.
