Fold MASK_LOAD/STORE with an all-true mask
This patch folds IFN_MASK_LOAD and IFN_MASK_STOREs to normal accesses
if the mask is all-true. This can happen for fully-masked loops that
didn't actually need to be (which could be handled by the vectoriser
instead), or for unrolled fully-masked loops whose first iteration is
guaranteed to operate on a full vector. It's also useful when the
accesses are generated directly by intrinsics (to follow for SVE).
