This patch changes the SLP lists grouped_stores and reduction_chains
from auto_vec<gimple *> to auto_vec<stmt_vec_info>. It was easier
to do them together due to the way vect_analyze_slp is structured.

gcc/
* tree-vectorizer.h (vec_info::grouped_stores): Change from
an auto_vec<gimple *> to an auto_vec<stmt_vec_info>.
(_loop_vec_info::reduction_chains): Likewise.
* tree-vect-loop.c (vect_fixup_scalar_cycles_with_patterns): Update
accordingly.
* tree-vect-slp.c (vect_analyze_slp): Likewise.
