Remove STMT_VINFO_SAME_ALIGN_REFS
This makes the only consumer of STMT_VINFO_SAME_ALIGN_REFS, the
loop peeling for alignment code, use locally computed data and
then removes STMT_VINFO_SAME_ALIGN_REFS and its computation.
It also adjusts the auto_vec<> move CTOR/assignment so you
can write
auto_vec<..> foo = bar.copy ();
and have foo own the generated copy.
