Add missing SLP discovery for CFN[_MASK][_LEN]_SCATTER_STORE
This was responsible for a bunch of SVE FAILs with --param vect-force-slp=1
* tree-vect-slp.cc (arg1_arg3_map): New.
(arg1_arg3_arg4_map): Likewise.
(vect_get_operand_map): Handle IFN_SCATTER_STORE,
IFN_MASK_SCATTER_STORE and IFN_MASK_LEN_SCATTER_STORE.
(vect_build_slp_tree_1): Likewise.
* tree-vect-stmts.cc (vectorizable_store): For SLP masked
gather/scatter record the mask with proper number of copies.
* tree-vect-loop.cc (vectorizable_recurr): Avoid costing
the initial value construction in the prologue twice with SLP.
