OpenBLAS has problems with incX==0 and/or incY==0 for DSWAP and DAXPY (I don't know for SSWAP, SAXPY, and complex functions). But for DSWAP and DAXPY the erroneous behavior is random: sometimes runs as refblas and sometimes runs wrong.

    Closed by 78da0e0. Disable multi-thread swap when incx==0 or incy==0.
