Harden SLP reduction support wrt STMT_VINFO_REDUC_IDX
The following makes sure that for a SLP reductions all lanes have
the same STMT_VINFO_REDUC_IDX. Once we move that info and can adjust
it we can implement swapping. It also makes the existing protection
against operand swapping trigger for all stmts participating in a
reduction, not just the final one marked as reduction-def.
* tree-vect-slp.cc (vect_build_slp_tree_1): Compare
STMT_VINFO_REDUC_IDX.
(vect_build_slp_tree_2): Prevent operand swapping for
all stmts participating in a reduction.
