tree-optimization/98211 - fix bogus vectorization of conversion
Pattern recog incompletely handles some bool cases but we shouldn't
miscompile as a result but not vectorize. Unfortunately
vectorizable_assignment lets invalid conversions (that
vectorizable_conversion rejects) slip through. The following
rectifies that.

* tree-vect-stmts.c (vectorizable_assignment): Disallow
invalid conversions to bool vector types.
* gcc.dg/pr98211.c: New testcase.
