I don't know the history about it.  I guess that the original
intention would be to use FP registers as fast memories for
integers, though I'm wrong about it.  BTW, the last time I
tried to disable integer mode for FP registers, some reload
failures popped up in gcc testsuite.  Are there no new failures
on your test with the above patch?
