	* infrun.c (wait_for_inferior): Mark registers as invalid when
	stepping over an instruction that triggered a watchpoint.
	* remote-mips.c: Numerous changes to support hardware breakpoints
	and watchpoints on LSI MiniRISC and TinyRISC boards.
	* mips-tdep.c: Move MIPS16-related macros to config/mips/tm-mips.h.
	(mips_breakpoint_from_pc): Account for different breakpoint
	instructions used by PMON and IDT monitor.
	* config/mips/tm-embed.h: Enable hardware breakpoints on embedded
	MIPS targets.
	* config/mips/tm-mips.h: Define breakpoint instructions for
	PMON and IDT monitor.  Move MIPS16-related macros here from
	mips-tdep.c.
