* config/tc-m68hc11.c (elf_flags): Set default ABI to gcc default

	(32-bit int, 64-bit double).
	(md_longopts): New options -mshort, -mlong, -mshort-double and
	-mlong-double to control the ABI.
	(md_show_usage): Update.
	(md_parse_option): Handle new options.
	* doc/as.texinfo (Overview): Document new options for HC11/HC12.
