Hi!
The recent change in find_assert_locations from XCNEWVEC to XNEWVEC
caused a valgrind warning, because bb_rpo[ENTRY_BLOCK] used to
be accessed, but was never initialized.
Fixed by ignoring edges from ENTRY_BLOCK altogether.
The rest are a couple of memory leak fixes.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* tree-vrp.c (find_assert_locations): Skip also edges
from the entry block.
* tree-vect-loop-manip.c (slpeel_make_loop_iterate_ntimes): Call
free_stmt_vec_info on orig_cond after gsi_removing it.
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment): Always
free body_cost_vec vector.
(vect_analyze_data_refs): If gather is unsuccessful,
free_data_ref (dr).
* tree-inline.c (tree_function_versioning): Free
old_transforms_to_apply vector.
