    tree-optimization/123755 - properly register loop mask for trapping call

    The following makes sure to register a loop mask if we mask the loop
    because the call could trap.

            PR tree-optimization/123755
            * tree-vect-stmts.cc (vectorizable_call): Register mask when
            the call could trap.

            * gcc.dg/vect/vect-pr123755.c: New testcase.
