    Another ICE after conflicting types of redeclaration [PR109619]

    This another one of these ICE after error issues with the
    gimplifier and a fallout from r12-3278-g823685221de986af.
    This case happens when we are trying to fold memcpy/memmove.
    There is already code to try to catch ERROR_MARKs as arguments
    to the builtins so just need to change them to use error_operand_p
    which checks the type of the expression to see if it was an error mark
    also.

    Bootstrapped and tested on x86_64-linux-gnu with no regressions.

    gcc/ChangeLog:

            PR c/109619
            * builtins.cc (fold_builtin_1): Use error_operand_p
            instead of checking against ERROR_MARK.
            (fold_builtin_2): Likewise.
            (fold_builtin_3): Likewise.

            * gcc.dg/redecl-26.c: New test.
