re PR target/23683 (review all uses of gen_rtx_MEM in sh port) 

	PR target/23683
	* sh.c (sh_reorg, emit_load_ptr): Use gen_const_mem.
	(output_stack_adjust): Use gen_tmp_stack_mem.
	(sh_expand_prologue, sh_expand_epilogue): Use gen_frame_mem.
	(sh_set_return_address, sh_allocate_initial_value): Likewise.
	(sh_get_pr_initial_val): Likewise.
	(sh_builtin_saveregs): Use gen_frame_mem and change_address.
	(sh_initialize_trampoline): Likewise.  Also use adjust_address.
	* sh.md (divsi_inv_m0): Use gen_const_mem.
	(push_fpscr, pop_fpscr, load_ra): Use gen_frame_mem.
	(movdf_i4+1): Use gen_tmp_stack_mem.
	(reload_outdf+3, reload_outdf+4, fpu_switch+1): Use change_address.
	(fpu_switch+2): Likewise.
	(movv4sf_i, movv16sf_i): Use adjust_address.
	(symGOT_load): Set MEM_NOTRAP_P bit.
