tree-call-cdce: If !HONOR_NANS do not make code with NaNs (PR88055)
If we don't HONOR_NANS we should not try to use any unordered
comparison results. Best case those will just be optimized away;
realistically, they ICE. For example, the rs6000 backend has some
code that specifically checks we never do this.
PR tree-optimization/88055
* tree-call-cdce.c (comparison_code_if_no_nans): New function.
(gen_one_condition): Use it if !HONOR_NANS.
