openmp: Fix max_vf testcases with -march=cascadelake

Apparently we need to explicitly disable AVX, not just enabled SSE, to
guarentee the 16-lane vectors we need for the pattern match.

libgomp/ChangeLog:

	* testsuite/libgomp.c/max_vf-1.c: Add -mno-avx.

gcc/testsuite/ChangeLog:

	* gcc.dg/gomp/max_vf-1.c: Add -mno-avx.
