[MIPS 17/30] Use gen_frame_mem and gen_const_mem


There were various calls to gen_rtx_MEM that would be better using
gen_frame_mem or gen_const_mem instead.

Richard


gcc/
	* config/mips/mips.c (mips_call_tls_get_addr): Use gen_const_mem
	rather then gen_rtx_MEM.
	(mips_setup_incoming_varargs): Use gen_frame_mem rather than
	gen_rtx_MEM.
	(mips_set_return_address): Likewise.
	(mips_restore_gp): Likewise.
