[Bug optimization/14196] New: [tree-ssa] ICE with __builtin_isgreater

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following code snippet causes an ICE when compiled with "-O -ffast-math":

=====================================================
double foo() { return __builtin_isgreater(0.,0.); }
=====================================================

bug.c: In function `foo':
bug.c:1: internal compiler error: in invert_tree_comparison, at
fold-const.c:2012
Please submit a full bug report, [etc.]

A similar problem was fixed in gcc 3.1 (see PR4765).

Jeff, your patch

http://gcc.gnu.org/ml/gcc-cvs/2004-02/msg00584.html

seems to be responsible for the regression.
Could you please have a look?
