i386: Fix up V2DI and V1TI inequality comparisons [PR105613]

The recent r13-458 change to introduce vec_cmpeqv1tiv1ti and
add TARGET_SSE2 support to vec_cmpeqv2div2di works nicely for
equality comparisons, but as the testcase shows doesn't work
for inequality comparisons.
For EQ if we perform comparison with twice as many half-sized elemenets,
the result should be ~0 when both halves are ~0 only (both halves need
to be equal for the whole to be equal), otherwise 0, so AND is the
correct operation for it.
But for NE, the result should be ~0 when either of the halves is ~0
(if either half is not equal, the whole is not equal) and so the right
operation for NE is IOR, not AND.

	PR target/105613
	* config/i386/sse.md (vec_cmpeqv2div2di, vec_cmpeqv1tiv1ti): Use
	andv4si3 only for EQ, for NE use iorv4si3 instead.

	* gcc.c-torture/execute/pr105613.c: New test.
