* gdbarch.sh (PUSH_DUMMY_CODE): New architecture method, add
	comments noteing that it replaces the old FIX_CALL_DUMMY code.
	* gdbarch.h, gdbarch.c: Re-generate.
	* d10v-tdep.c (d10v_push_dummy_code): New function.
	(d10v_gdbarch_init): Set push_dummy_code.
	* infcall.c (legacy_push_dummy_code): New function.
	(generic_push_dummy_code): New function.
	(push_dummy_code): New function.
	(call_function_by_hand): Call push_dummy_code.  Pass bp_addr,
	instead of dummy_addr, to push_dummy_call.  Move call to
	generic_save_call_dummy_addr to outside of CALL_DUMMY_LOCATION
	switch.
	* sparc-tdep.c (sparc_gdbarch_init): Mention push_dummy_code.

	* gdbint.texinfo (Target Architecture Definition): Document
	push_dummy_code.  Add cross references.
