New description:
See #11226 and [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48823].
For sympow, we need to use the compiler option `-ffp-contract=on`, `-mno-
fused-madd` or `-ffloat-store` (if the compiler supports it).
Sympow should also create its datafiles, see #5155.

Comment:
leif: I took care of most of your comments. It now uses "-ffloat-store"
if needed.
