I've split up the FPCR as requested by Aurelien. We no longer
set anything in FP_STATUS after the execution of the operation,
only copy data from FP_STATUS to some env->fpcr field.
I have totally rewritten the patch to be more along the line
that Laurent was suggesting, in that the rounding mode and other
qualifiers are totally parsed within the translator. I no longer
pass the FN11 field to the helper functions.
Unlike Laurent's prototype, I do not set the rounding mode at
every FP instruction; I remember the previous setting of the
rounding mode within a TB. Similarly for the flush-to-zero field.
I do not handle VAX instructions at all. The existing VAX support
is mostly broken, and I didn't feel like compounding the problem.
