Fortran: optional argument DIM for intrinsics NORM2, PARITY must be scalar
gcc/fortran/ChangeLog:
PR fortran/104212
* check.cc (gfc_check_norm2): Check that optional argument DIM is
scalar.
(gfc_check_parity): Likewise.
gcc/testsuite/ChangeLog:
PR fortran/104212
* gfortran.dg/argument_checking_26.f90: New test.
