(order_regs_for_local_alloc): Add casts to bcopy call.
(print_operand, case 'f'): New case.
(sparc_initialize_trampoline): Use gen_flush instead of knowing what pattern
looks like.
Use MEM instead of address in flush insn, so virtual reg instantiation can
update.
Ensure address in flush insn is valid.
