real.h (HONOR_SNANS, [...]): Replace macros with 3 overloaded declarations.

2014-12-12  Marc Glisse  <marc.glisse@inria.fr>

	* real.h (HONOR_SNANS, HONOR_INFINITIES, HONOR_SIGNED_ZEROS,
	HONOR_SIGN_DEPENDENT_ROUNDING): Replace macros with 3 overloaded
	declarations.
	* real.c (HONOR_NANS): Fix indentation.
	(HONOR_SNANS, HONOR_INFINITIES, HONOR_SIGNED_ZEROS,
	HONOR_SIGN_DEPENDENT_ROUNDING): Define three overloads.
	* builtins.c (fold_builtin_cproj, fold_builtin_signbit,
	fold_builtin_fmin_fmax, fold_builtin_classify): Simplify argument
	of HONOR_*.
	* fold-const.c (operand_equal_p, fold_comparison, fold_binary_loc):
	Likewise.
	* gimple-fold.c (gimple_val_nonnegative_real_p): Likewise.
	* ifcvt.c (noce_try_move, noce_try_minmax, noce_try_abs): Likewise.
	* omp-low.c (omp_reduction_init): Likewise.
	* rtlanal.c (may_trap_p_1): Likewise.
	* simplify-rtx.c (simplify_const_relational_operation): Likewise.
	* tree-ssa-dom.c (record_equality, record_edge_info): Likewise.
	* tree-ssa-phiopt.c (value_replacement, abs_replacement): Likewise.
	* tree-ssa-reassoc.c (eliminate_using_constants): Likewise.
	* tree-ssa-uncprop.c (associate_equivalences_with_edges): Likewise.
