Fix PR 101237: Remove element_type call when used with the functions from real

HONOR_SIGNED_ZEROS, HONOR_SIGN_DEPENDENT_ROUNDING, and HONOR_SNANS all
have an overload for taking a tree type now, so we should do that instead.

OK?  Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

	PR middle-end/101237
	* fold-const.c (negate_expr_p): Remove call to element_mode
	and TREE_MODE/TREE_TYPE when calling HONOR_SIGNED_ZEROS,
	HONOR_SIGN_DEPENDENT_ROUNDING, and HONOR_SNANS.
	(fold_negate_expr_1): Likewise.
	(const_unop): Likewise.
	(fold_cond_expr_with_comparison): Likewise.
	(fold_binary_loc): Likewise.
	(fold_ternary_loc): Likewise.
	(tree_call_nonnegative_warnv_p): Likewise.
	* match.pd (-(A + B) -> (-B) - A): Likewise.
