Fortran: catch failed simplification of bad stride expression
gcc/fortran/ChangeLog:
PR fortran/103588
* array.c (gfc_ref_dimen_size): Do not generate internal error on
failed simplification of stride expression; just return failure.
gcc/testsuite/ChangeLog:
PR fortran/103588
* gfortran.dg/pr103588.f90: New test.
