s390: Emulate vec_cmp{eq,gt,gtu} for 128-bit integers

Mode iterator V_HW enables V1TI for target VXE which means
vec_cmpv1tiv1ti becomes available which leads to an ICE since there is
no corresponding insn.

Fixed by emulating comparisons and enabling mode V1TI unconditionally
for V_HW.  For the sake of symmetry, I also added TI mode to V_HW since
TF mode is already included.  As a consequence the consumers of V_HW
vec_{splat,slb,sld,sldw,sldb,srdb,srab,srb,test_mask_int,test_mask}
also become available for 128-bit integers.

This fixes gcc.c-torture/execute/pr105613.c and gcc.dg/pr106063.c.

gcc/ChangeLog:

	* config/s390/vector.md (V_HW): Enable V1TI unconditionally and
	add TI.
	(vec_cmpu<VIT_HW:mode><VIT_HW:mode>): Add 128-bit integer
	variants.
	(*vec_cmpeq<mode><mode>_nocc_emu): Emulate operation.
	(*vec_cmpgt<mode><mode>_nocc_emu): Emulate operation.
	(*vec_cmpgtu<mode><mode>_nocc_emu): Emulate operation.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/vector/vec-cmp-emu-1.c: New test.
	* gcc.target/s390/vector/vec-cmp-emu-2.c: New test.
	* gcc.target/s390/vector/vec-cmp-emu-3.c: New test.
