Some minor HONOR_NANS improvements to match.pd
Tweak the constant folding of X CMP X in when X can't be a NaN.
2022-03-16 Roger Sayle <roger@nextmovesoftware.com>
gcc/ChangeLog
* match.pd (X CMP X -> true): Test tree_expr_maybe_nan_p
instead of HONOR_NANS.
(X LTGT X -> false): Enable if X is not tree_expr_maybe_nan_p, as
this can't trap/signal.
