Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

defines one function, gofast_maybe_init_libfuncs, which should be

US_SOFTWARE_GOFAST, this function will adjust all the optabs and

FP-emulation library returns +1 for both > and unord. So we
leave gt and ge unset, such that, instead of fpcmp(a,b) >[=], we
generate fpcmp(b,a) <[=] 0, which is unambiguous. For unord
libfuncs, we use our own functions, since GOFAST doesn't supply
them. */
