Marcel Moolenaar 28466ae036 Fix handling of FP traps: 
o  For traps, the cr.iip register points to the next instruction to
   execute on interrupt return (modulo slot). Since we need to get
   the bundle of the instruction that caused the FP fault/trap, make
   sure we fetch the previous bundle if the next instruction is in
   fact the first in a bundle.
o  When we call the FPSWA handler, we need to tell it whether it's
   a trap or a fault (first argument). This was hardcoded to mean a
   fault.

Also, for FP faults, when a fault is converted to a trap, adjust the
cr.iip and cr.ipsr registers to point to the next instruction. This
makes sure that the SIGFPE handler gets a consistent state.
