* sysdeps/x86_64/fpu/feenablxcpt.c (feenableexcept): Remove dead code.
* sysdeps/x86_64/fpu/fedisblxcpt.c (fedisableexcept): Likewise.
* sysdeps/i386/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions
in MXCSR if SSE is available.

Return 0 rather than 1.
* sysdeps/ia64/fpu/feupdateenv.c (feupdateenv): Fix comment typo.
Remove incorrect part of a comment. Fix argument to feraiseexcept.
