This additional patch solves GCC PR 28796, It's originally
from Apple's GCC so it's also covered by the GPL2.

* builtins.c (fold_builtin_classify): Use HONOR_INFINITIES
and HONOR_NANS instead of MODE_HAS_INFINITIES and MODE_HAS_NANS
for deciding optimizations in consistency with fold-const.c
(fold_builtin_unordered_cmp): Likewise.
