poly_int: vectorizable_load/store
This patch makes vectorizable_load and vectorizable_store cope with
variable-length vectors. The reverse and permute cases will be
excluded by the code that checks the permutation mask (although a
patch after the main SVE submission adds support for the reversed
case). Here we also need to exclude VMAT_ELEMENTWISE and
VMAT_STRIDED_SLP, which split the operation up into a constant
number of constant-sized operations. We also don't try to extend
the current widening gather/scatter support to variable-length
vectors, since SVE uses a different approach.

* tree-vect-stmts.c (get_load_store_type): Treat the number of
units as polynomial. Reject VMAT_ELEMENTWISE and VMAT_STRIDED_SLP
for variable-length vectors.
(vectorizable_mask_load_store): Treat the number of units as
polynomial, asserting that it is constant if the condition has
already been enforced.
(vectorizable_store, vectorizable_load): Likewise.
