re PR fortran/86421 (OpenMP declare simd linear ref in module causes gfortran to...

	PR fortran/86421
	* module.c (omp_declare_simd_clauses): Add LINEAR with _REF, _VAL and
	_UVAL suffixes.
	(mio_omp_declare_simd): Save and restore ref, val and uval modifiers
	on linear clauses.  Initialize n->where to gfc_current_locus.

	* gfortran.dg/vect/pr86421.f90: New test.
