Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new variable, float_exception_mask (#defined to _softfloat_float_exception_mask) contains the current exception mask. Also make the argument to float_raise into an fp_except. Also synchronise file header comments between files.

/* $NetBSD: softfloat-for-gcc.h,v 1.5 2002/05/12 13:12:45 bjh21 Exp $ */
Initial commit of SoftFloat 2a import. This should provide a sensible mostly-MI floating-point implementation for use by gcc -msoft-float. It's currently only used by arm26, but should be usable by other ports without too much hacking, assuming doubles and u_int64_ts are passed and returned the same way, and FP formats are IEEEish.

Re-instate __fixunssfsi() and __fixunsdfsi(), but only for arm32 with a.out binaries, because libc's provided them there forever.
