I'm trying to make a testcase out of PovRay sources that trigger this behaviour.
I think that "*movdf_nointeger" is somehow confused and chooses SSE register to
load constant. After that, reload moves SSE reg to FP reg via stack. Perhaps
ix86_preferred_reload_class () needs some fine-tuning regarding to -mfpmath
parameter?
