rtl.h (loc_mentioned_in_p): Declare.

	* rtl.h (loc_mentioned_in_p): Declare.
	* reload.c (loc_mentioned_in_p): Moved from here...
	* rtlanal.c (loc_mentioned_in_p): to here.  No longer static.
	Fix loop increment for 'E' handling.
	* loop.c (strength_reduce): When doing biv->giv conversion,
	take multi-insn biv increments into account.
