Fix uninitialized LOOP_VINFO_LOOP_IV_COND

Browse Source 
With uncounted loop support we can leave LOOP_VINFO_LOOP_IV_COND
uninitialized but that's accessed from vect_stmt_relevant_p,
unlikely to match by chance, but the following fixes it nevertheless.

	* tree-vect-loop.cc (_loop_vec_info::_loop_vec_info):
	Initialize loop_iv_cond given it's no longer always
	initialized ...
	(vect_create_loop_vinfo): ... here.  Fix formatting.
