Richard Henderson	4223c9c1c6	tcg/s390x: Implement TCG_TARGET_HAS_sat_vec ... The unsigned saturations are handled via generic code using min/max. The signed saturations are expanded using double-sized arithmetic and a saturating pack. Since all operations are done via expansion, do not actually set TCG_TARGET_HAS_sat_vec.

Richard Henderson	34ef767609	tcg/s390x: Add host vector framework ... Add registers and function stubs. The functionality is disabled via squashing s390_facilities[2] to 0. We must still include results for the mandatory opcodes in tcg_target_op_def, as all opcodes are checked during tcg init.
