* tree-vect-stmts.c (vectorizable_shift): If op1 is vect_external_def
in a loop and has different type from op0, cast it to op0's type
before the loop first.  For slp give up.  Don't crash if op1_vectype
is NULL.

* gcc.dg/vshift-3.c: New test.
* gcc.dg/vshift-4.c: New test.
* gcc.dg/vshift-5.c: New test.
