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.

* tree-vect-slp.c (vect_schedule_slp_node): Handle the
case where last_stmt alters control flow.
* g++.dg/vect/pr105437.cc: New testcase.
