[PATCH] Fix memory leak in vect_cse_slp_nodes

[Richard Biener]

The following avoids copying scalar stmts again for the re-lookup
of the slot to replace the NULL guard with node.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

Richard.

        * tree-vect-slp.cc (vect_cse_slp_nodes): Fix memory leak.
