    • Make vectorizable_load/store handle IFN_MASK_LOAD/STORE · c3a8f964 
      After the previous patches, it's easier to see that the remaining
inlined transform code in vectorizable_mask_load_store is just a
cut-down version of the VMAT_CONTIGUOUS handling in vectorizable_load
and vectorizable_store.  This patch therefore makes those functions
handle masked loads and stores instead.

This makes it easier to handle more forms of masked load and store
without duplicating logic from the unmasked forms.  It also helps with
support for fully-masked loops.

    • Split gather load handling out of vectorizable_{mask_load_store,load} · c48d2d35 
      vectorizable_mask_load_store and vectorizable_load used the same
code to build a gather load call, except that the former also
vectorised a mask argument and used it for both the merge and mask
inputs.  The latter instead used a merge input of zero and a mask
input of all-ones.  This patch splits it out into a subroutine.

    • Split out gather load mask building · bc9587eb 
      This patch splits out the code to build an all-bits-one or all-bits-zero
input to a gather load.  The catch is that both masks can have
floating-point type, in which case they are implicitly treated in
the same way as an integer bitmask.

    • Split mask checking out of vectorizable_mask_load_store · aaeefd88 
      This patch splits the mask argument checking out of
vectorizable_mask_load_store, so that a later patch can use it in both
vectorizable_load and vectorizable_store.  It also adds dump messages
for false returns.  This is mostly useful for the TYPE_VECTOR_SUBPARTS
check, which can fail if pattern recognition didn't convert the mask
properly.

    • Make vect_model_store_cost take a vec_load_store_type · 9ce4345a 
      This patch makes vect_model_store_cost take a vec_load_store_type
instead of a vect_def_type.  It's a wash on its own, but it helps
with later patches.

    • Move code that stubs out IFN_MASK_LOADs · e251d3ec 
      vectorizable_mask_load_store replaces scalar IFN_MASK_LOAD calls with
dummy assignments, so that they never survive vectorisation.  This patch
moves the code to vect_transform_loop instead, so that we only change
the scalar statements once all of them have been vectorised.

This makes it easier to handle other types of functions that need
stubbing out, and also makes it easier to handle groups and patterns.
