Replace the unmaintainable assembler code responsible for 88100 precise FPU
fault handling with a C wrapper around the softfloat code, as already done for
88110 kernels.
As a bonus, attempting to read or write FPU control registers but fcr62 and
fcr63 in userland will now correctly signal an illegal instruction, instead
of leaving the destination register unchanged and pretending nothing bad
happened.
Be sure to rm m88100_fp.d in your kernel compile directory after updating your
tree.

Override SoftFloat's countLeadingZeros32() with a faster, ff1-based, version
on m88k.

Had I known we had a kernel version of John Hauser's SoftFloat code, I would
have jumped on it instead of basing the FPU completion work on the sparc
FPU code.
This is now repaired with this commit, and m88110_fp.c changes directory
again, for the last time.
