[Bug target/19506] [4.0 Regression] PovRay produces wrong pictures with -mfpmath=sse -ffast-math.

I've found the problem, via binary search on the povray source and then 
visual inspection of the file found to be miscompiled.  The mov[sd]fcc_1_sse
patterns are missing an earlyclobber.  The fix isn't quite as simple as just
adding '&' to the pattern, but I should have it done today.
