ae77bbe574 tcg/s390x: Implement andc, orc, abs, neg, not vector operations

a429ee2978 tcg/s390x: Implement minimal vector operations
Implementing add, sub, and, or, xor as the minimal set.
This allows us to actually enable vectors in query_s390_facilities.

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.

They are rightly values in the same enumeration.

748b7f3ef7 tcg/s390x: Change FACILITY representation
We will shortly need to be able to check facilities beyond the
first 64.  Instead of explicitly masking against s390_facilities,
create a HAVE_FACILITY macro that indexes an array.

This emphasizes that we don't support s390, only 64-bit s390x hosts.
