This is the main patch in the series. It adds a new enum and routines
for classifying a vector load or store implementation.
Tested on aarch64-linux-gnu and x86_64-linux-gnu. OK to install?
Thanks,

gcc/
* tree-vectorizer.h (vect_memory_access_type): New enum.
(_stmt_vec_info): Add a memory_access_type field.
(STMT_VINFO_MEMORY_ACCESS_TYPE): New macro.
(vect_model_store_cost): Take an access type instead of a boolean.
(vect_model_load_cost): Likewise.
* tree-vect-slp.c (vect_analyze_slp_cost_1): Update calls to
vect_model_store_cost and vect_model_load_cost.
* tree-vect-stmts.c (vec_load_store_type): New enum.
(vect_model_store_cost): Take an access type instead of a
store_lanes_p boolean. Simplify tests.
(vect_model_load_cost): Likewise, but for load_lanes_p.
(get_group_load_store_type, get_load_store_type): New functions.
(vectorizable_store): Use get_load_store_type. Record the access
type in STMT_VINFO_MEMORY_ACCESS_TYPE.
(vectorizable_load): Likewise.
(vectorizable_mask_load_store): Likewise. Replace is_store
variable with vls_type.
OK. Looks like a nice cleanup to me. If there's something that got
goof'd along the way, I trust you'll deal with it appropriately -- I
didn't try to map from every conditional back in the original code to
the conditionals in the new code.
