    fold: Change comparison of error_mark_node to use error_operand_p in
tree_expr_nonnegative_warnv_p [PR118948]

    This is an obvious fix for this small regression. Basically after
r15-328-g5726de79e2154a,
    there is a call to tree_expr_nonnegative_warnv_p where the type of the
expression is now
    error_mark_node. Though there was only a check if the expression was
error_mark_node.

    Bootstrapped and tested on x86_64-linux-gnu.

    gcc/ChangeLog:

            * fold-const.cc (tree_expr_nonnegative_warnv_p): Use
            error_operand_p instead of checking for error_mark_node directly.

    gcc/testsuite/ChangeLog:

            * gcc.dg/pr118948-1.c: New test.
