Hi,

This patch extends dumps for vectorized loops to provide more info
about them and also specify used vector size.  This is to be used
for tests.

Thanks,
Ilya

	* tree-vect-loop.c (vect_transform_loop): Print more info
	about vectorized loop and specify used vector size.

OK when the rest of the dependent work is approved.
