* config/m68k/m68k.h (MACHINE_STATE_SAVE): #ifdef USE_GAS use
`%' as prefix for register names.
Rather than add more cases, I have modified the existing cases to use
the %# (IMMEDATE_PREFIX) and %/ (REGISTER_PREFIX) modifiers, which means
that they should now be correct for any assembler.

* m68k.h (MACHINE_STATE_SAVE, MACHINE_STATE_RESTORE): In MOTOROLA
cases, add %# and %/, and add : to make them into extended asms.
