powerpcspe: Implement SPE exception handling

The Signal Processing Engine (SPE) found in Freescale e500 cores (and
others) offloads IEEE-754 compliance (NaN, Inf handling, overflow,
underflow) to software, most likely as a means of simplifying the APU
silicon.  Some software, like AbiWord, needs full IEEE-754 compliance,
including NaN handling.  Implement the necessary bits to enable it.
