	PR fortran/48955
	* trans-expr.c (gfc_trans_assignment_1): GFC_REVERSE_NOT_SET
	changed to GFC_ENABLE_REVERSE.
	* trans-array.c (gfc_init_loopinfo): GFC_CANNOT_REVERSE changed
	to GFC_INHIBIT_REVERSE.
	* gfortran.h : Enum gfc_reverse is now GFC_ENABLE_REVERSE,
	GFC_FORWARD_SET, GFC_REVERSE_SET and GFC_INHIBIT_REVERSE.
	* dependency.c (gfc_dep_resolver): Change names for elements of
	gfc_reverse as necessary. Change the logic so that forward
	dependences are remembered as well as backward ones. When both
	have appeared, force a temporary.
