Bruce Evans f107f876a6 Separate fpresetsticky() from the other fpset functions so that the
others can be replaced cleanly by the amd64 versions.   There is no
current amd64 version to merge, but there is an old one which is
similar.

Fix the following bugs in fpresetsticky():
- garbage args clobbered non-sticky bits in the status register
- the return value was usually garbage since it was masked with the
  arg instead of with the field selector.

Optimize fpresetsticky() to avoid using the environment as in
feclearexcept() (use only fnclex() if possible) and also to avoid
using fnclex() for null changes.  The second of these optimizations
might not be so good since its branch might cost more than it saves.
