[pach, Fortran] Improve dependency checking

[Thomas Koenig]

Hello world,

here's another installment of dependency checking improvements.

I debated a little with myself if extending gfc_ref_dimen_size really
was the right approach, but I didn't want to duplicate its code.

Regression-tested on trunk.  OK?

[If there isn't time to review this before tomorrow evening, I would
ask somebody to commit this for me].

	PR fortran/44235
	* array.c (gfc_ref_dimen_size):  Add end argument.
	If end is non-NULL, calculate it.
	(ref_size):  Adjust call to gfc_ref_dimen_size.
	(gfc_array_dimen_size):  Likewise.
	(gfc_array_res_shape):  Likewise.
	* gfortran.h:  Adjust prototype for gfc_ref_dimen_size.
	* resolve.c (resolve_array_ref):  For stride not equal to -1,
	fill in the lowest possible end.
