poly_int: vectorizable_live_operation

This patch makes vectorizable_live_operation cope with variable-length
vectors.  For now we just handle cases in which we can tell at compile
time which vector contains the final result.

gcc/
	* tree-vect-loop.c (vectorizable_live_operation): Treat the number
	of units as polynomial.  Punt if we can't tell at compile time
	which vector contains the final result.
