Harald Anlauf cd6cd6aed1 PR libfortran/97063 - Wrong result for vector (step size is negative) * matrix 
The MATMUL intrinsic provided a wrong result for rank-1 times rank-2 array
when a negative stride was used for addressing the elements of the rank-1
array, because a check on strides was erroneously placed before the check
on the rank.  Interchange order of checks.

libgfortran/ChangeLog:

	* m4/matmul_internal.m4: Move check for rank-1 times rank-2 before
	checks on strides for rank-2 times rank-2.
	* generated/matmul_c10.c: Regenerated.
	* generated/matmul_c16.c: Likewise.
