Adjust reduction with conversion SLP build
The following adjusts how we set SLP_TREE_VECTYPE for the conversion
node we build when fixing up the reduction with conversion SLP instance.
This should probably see more TLC, but the following avoids relying
on STMT_VINFO_VECTYPE for this.
* tree-vect-slp.cc (vect_build_slp_instance): Do not use
SLP_TREE_VECTYPE to determine the conversion back to the
reduction IV.
