Clean up PURE_SLP_STMT handling

The vectorizable_* routines had many instances of:

        slp_node || PURE_SLP_STMT (stmt_info)

which gives the misleading impression that we can have
!slp_node && PURE_SLP_STMT (stmt_info).  In this context
it's really enough to test slp_node on its own.

There are three cases:

      loop vectorisation only:
        vectorizable_foo called only with !slp_node

      pure SLP:
        vectorizable_foo called only with slp_node

      hybrid SLP:
        (e.g. a vector that's used in SLP statements and also in a reduction)
        - vectorizable_foo called once with slp_node for the SLP uses.
        - vectorizable_foo called once with !slp_node for the non-SLP uses.

Hybrid SLP isn't possible for stores, so I added an explicit assert
for that.

I also made vectorizable_comparison static, to make it obvious that
no other callers outside tree-vect-stmts.c could use it with the
!slp && PURE_SLP_STMT combination.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.

Avoid unnecessary peeling for gaps with LD3

vectorizable_load forces peeling for gaps if the vectorisation factor
is not a multiple of the group size, since in that case we'd normally load
beyond the original scalar accesses but drop the excess elements as part
of a following permute:

          if (loop_vinfo
              && ! STMT_VINFO_STRIDED_P (stmt_info)
              && (GROUP_GAP (vinfo_for_stmt (first_stmt)) != 0
                  || (!slp && vf % GROUP_SIZE (vinfo_for_stmt (first_stmt)) != 0)))

This isn't necessary for LOAD_LANES though, since it loads only the
data needed and does the permute itself.
