add the early-clobber modifier on the destination reg of ldstub. in some implementations (eg. sun4c), the hardware modifies the destination reg before checking for write permission on the memory location. without this change, gcc was using the same register for the address and the destination, so if the store part of the instruction faulted, the address was already gone when the instruction was retried after resolving the fault. part of PR 25633, PR 25896.
