* Makefile.in sh3-rom.c config/sh/sh.mt config/sh/tm-sh.h: Add

	sh3 monitor support.
	* monitor.c:  Cleanup regexp compilation stuff to make it easier
	to use several regexps.
	* monitor.h:  Get rid of struct rom_cmd_data.  It's no longer used.
	* config/m68k/tm-monitor.h:  Don't redefine NUM_REGS here.  It just
	causes GDB to crash.
