Fix gcc2 irix5 c-torture failures, EH/large frame errors
	* mips/mips.c (save_restore_insns): If gp_offset or fp_offset are
	large_int, emit two insns instead of one splitable insn.
	* dwarf2out.c (dwarf2out_frame_debug): When set cfa_store_offset
	from cfa_temp_value, use cfa_offset.  Add assert checking that
	cfa_reg is SP.
