vect_analyze_loop_operations was calling vectorizable_live_operation
for all live-out phis, which led to a bogus ncopies calculation in
the pure SLP case.  I think v_a_l_o should only be passing phis
that are vectorised using normal loop vectorisation, since
vect_slp_analyze_node_operations handles the SLP side (and knows
the correct slp_index and slp_node arguments to pass in, via
vect_analyze_stmt).

With that fixed we hit an older bug that vectorizable_live_operation
didn't handle live-out SLP inductions.  Fixed by using gimple_phi_result
rather than gimple_get_lhs for phis.

The port-local FUNCTION_ARG_SIZE:

  ((((MODE) != BLKmode \
     ? (HOST_WIDE_INT) GET_MODE_SIZE (MODE) \
     : int_size_in_bytes (TYPE)) + UNITS_PER_WORD - 1) / UNITS_PER_WORD)

Treating GET_MODE_SIZE as a constant is OK for the former but not
the latter, which is used in target-independent code.  This caused

We had:

	      tree t = fold_vec_perm (type, arg1, arg2,
				      vec_perm_indices (sel, 2, nelts));

where fold_vec_perm takes a const vec_perm_indices &.  GCC 4.1 apparently
required a public copy constructor:

gcc/vec-perm-indices.h:85: error: 'vec_perm_indices::vec_perm_indices(const vec_perm_indices&)' is private

even though no copy should be made here.  This patch tries to work

In the testcase we were trying to group two gather loads, even though
that isn't supported.  Fixed by explicitly disallowing grouping of

This problem didn't show up on SVE because there we convert to
