I don't see any *fma* failures on current trunk, neither i686-linux nor
x86_64-linux.  Can this be closed now?

When configured with --with-cpu=atom, I got

since -mtune=atom disables double precision vectorizer.
We need to pass -mtune=generic to those 2 testcases.

The patch to add -mtune=generic to dg-options in preapproved.
