Richard's comment:
I think this part of the patch is OK. SLP_TREE_VEC_STMTS and
STMT_VINFO_VEC_STMT should only receive the final stmt for each vector
result, whereas these stmts are producing intermediate results.
The assignments were introduced as part of a mechanical patch to avoid
using vinfo_for_stmt to get stmt_infos that we'd just created. I'd
missed that in these cases we didn't actually use vinfo_for_stmt.
Off-hand, I'm not sure whether we actually need to create the
stmt_info here as things stand, or whether we're really just using
vect_finish_stmt_generation to insert the stmt in the right way.
I did have some WIP patches that would need the stmt_info to be
created though.
So that I'm going to do the dead code removal.
