This was fixed for 4.8 by Jan Hubicka's r193175, which rewrote finite_loop_p in
tree-ssa-loop-niter.c. That patch doesn't work as-is in 4.7.2 (it applies but
uses other things which aren't in 4.7.2.)
The SEGV in 4.7.2 occurs in tree-vect-stmts.c:3938
3938 gcc_assert (useless_type_conversion_p (vectype,
3939 TREE_TYPE
(vec_oprnd)));
because vec_oprnd is NULL at that point.
