[Andreas Krebbel]

Testcases which override the vect default options using dg-options
need at least -mzarch on S/390 32 bit.

gcc/testsuite/ChangeLog:

2017-09-28  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* gfortran.dg/vect/fast-math-mgrid-resid.f: Use -mzarch on S/390.
	* gfortran.dg/vect/pr77848.f: Likewise.
