libm/remquo: Fix bug where wrong quotient was returned
Fix taken from FreeBSD:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=166463
https://cgit.freebsd.org/src/commit/lib/msun/src/s_remquo.c?id=1cbd288942b08217e99bf889e0967895d53af00c
FreeBSD commit message:
Fix a bug in remquo{,f,l}, in which the quotient didn't always have the
correct sign when the remainder was 0.
Fix a separate bug in remquo alone, in which the remainder and
quotient were both off by a bit in certain cases involving subnormal
remainders.
The bugs affected all platforms except amd64 and i386, on which the
routines are implemented in assembly.
(On NetBSD, this bug manifests on amd64.)
