* regcache.c (registers_changed_ptid): Don't explictly always

Browse Source 
clear `current_regcache'.  Only clear current_thread_ptid and
	current_thread_arch when PTID matches.  Only reinit the frame
	cache if PTID matches the current inferior_ptid.  Move alloca(0)
	call to ...
	(registers_changed): ... here.
