Deal with vector typed operands in conversions
The following avoids using TYPE_PRECISION on VECTOR_TYPE when
looking for bit-precision changes in vectorizable_assignment.
We didn't anticipate a stmt like
_21 = VIEW_CONVERT_EXPR<unsigned int>(vect__1.7_28);
and the following makes sure to handle that.
* tree-vect-stmts.cc (vectorizable_assignment):
Properly handle non-integral operands when analyzing
conversions.
