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

Unifdef NO_IEEE in the libkern softfloat code, and put an appropriate rule
in files.alpha to compensate for NO_IEEE kernels.

This will allow the softfloat code to be used by other platforms than alp

IEEE 754 floating point completion code, and implementation of the
FP_C (Floating Point Control Quadword).

From ross@NetBSD. Added a way to disable it with option NO_IEEE,
which appears on the ramdisks to save space. This affects only
programs compiled with -mieee, and what it essentially does is
enabling infinities and NaNs, instead of generating SIGFPE on
division by zero, overflow, etc.
ok art, deraadt
