Hi!
This test FAILs on i686-linux or e.g. sparc*-solaris*, because
it uses vect_int effective target outside of */vect/ testsuite.
That is wrong, vect_int assumes the extra added flags by vect.exp
by default, which aren't added in other testsuites.
The following patch fixes that by moving the test into gcc.dg/vect/
and doing small tweaks.
Regtested on x86_64-linux and i686-linux, ok for trunk?
