[Bug testsuite/34168] New: dg-require-effective-target vect_double doesn't work

["tkoenig at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I get

FAIL: gfortran.dg/vect/fast-math-pr33299.f90 execution test

Apparently, the check for  dg-require-effective-target vect_double
doesn't work.

This is on my Athlon XP 2600+, which does not have SSE2.  The
options for that test case do include the -msse2 flag, which is wrong:

Executing on host:
/home/ig25/gcc-bin/trunk/gcc/testsuite/gfortran/../../gfortran
-B/home/ig25/gcc-bin/trunk/gcc/tests
uite/gfortran/../../
/home/ig25/gcc/trunk/gcc/testsuite/gfortran.dg/vect/fast-math-pr33299.f90   -O2
-ftree-vectorize 
-ftree-vectorizer-verbose=4 -fdump-tree-vect-stats -msse2 -ffast-math 
-L/home/ig25/gcc-bin/trunk/i686-pc-linux-gnu/./
libgfortran/.libs
-L/home/ig25/gcc-bin/trunk/i686-pc-linux-gnu/./libgfortran/.libs
-L/home/ig25/gcc-bin/trunk/i686-pc-
linux-gnu/./libiberty  -lm   -o ./fast-math-pr33299.exe    (timeout = 300)

When I run the options by hand, I get an "illegal instruction"
error:
