    tree-optimization/105437 - BB vect with extern defs of throwing stmts

    We have to watch out for vectorized stmt insert locations if the
    def from the last stmt alters control flow.  We constrain region
    building so we know the def is outside of the current region
    and thus we can insert at the region start point.
