The following fixes a memory leak in vectorizable_store which happens
because the functions populating gvec_oprnds[i] will call .create ()
on the incoming vector, leaking what we've previously allocated.
Bootstrap and regtest running on x86_64-unknown-linux-gnu.
* tree-vect-stmts.cc (vectorizable_store): Do not allocate
storage for gvec_oprnds elements.
