Here is a fix. I'll be committing it at soon as I make sure it
doesn't effect any regressions. I ran, namd, libquantum, sphinx3 and
povray and they all completed the test input with the code sourcery tool
chain. You might want to switch to vfpv3 as it has a lot more
functionality and the vmov instructions end up being very useful.

see problems running some SPEC2006 benchmarks whereas I don't see the
same problems when I compile using software FP.
Thank you!
