* real.h (HONOR_NANS): Replace macro with 3 overloaded declarations.
* real.c: Include rtl.h and options.h.
(HONOR_NANS): Define three overloads.

Simplify argument of HONOR_NANS.
* fold-const.c (combine_comparisons, fold_truth_not_expr,
fold_cond_expr_with_comparison, merge_truthop_with_opposite_arm,
fold_comparison, fold_binary_loc): Likewise.
* ifcvt.c (noce_try_move, noce_try_minmax): Likewise.
* ipa-inline-analysis.c (add_clause,
set_cond_stmt_execution_predicate): Likewise.
* match.pd: Likewise.
* rtlanal.c (may_trap_p_1): Likewise.
* simplify-rtx.c (simplify_const_relational_operation): Likewise.
* tree-if-conv.c (parse_predicate): Likewise.
* tree-ssa-ccp.c (valid_lattice_transition): Likewise.
* tree-ssa-ifcombine.c (ifcombine_ifandif): Likewise.
* tree-ssa-phiopt.c (minmax_replacement, neg_replacement): Likewise.
