    Fix PR 101237: Remove element_type call when used with the functions fr=
om
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 inste=
ad.

    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.
