poly_int: vectorizable_conversion
This patch makes vectorizable_conversion cope with variable-length
vectors. We already require the number of elements in one vector
to be a multiple of the number of elements in the other vector,
so the patch uses that to choose between widening and narrowing.

* tree-vect-stmts.c (vectorizable_conversion): Treat the number
of units as polynomial. Choose between WIDE and NARROW based
on multiple_p.
