patch 9.1.0433: Wrong yanking with exclusive selection and ve=all

Browse Source 
Problem:  Wrong yanking with exclusive selection and virtualedit=all,
          and integer overflow when using getregion() on it.
Solution: Set coladd when decreasing column and 'virtualedit' is active.
          Add more tests for getregion() with 'virtualedit' (zeertzjq).
