This is v2 of the work that Al Viro helped with nearly a year ago.
At the time, I obsconded with an unused bit in the softfloat exception
flags. Which was a bit of a wart, and rightly pointed out as such
by someone at the time.
After 11 months on the shelf, I've finally found enough time to work
out the bugs in the re-implementation of the fpcr. This time all of
the bits are private to target-alpha, so no mucking about with the
generic softfloat code.
