David Hildenbrand 2cb8a68d37 s390x/tcg: Fix VECTOR SUBTRACT WITH BORROW INDICATION 
Testing this, there seems to be something messed up. We are dealing with
unsigned numbers. "Each operand is treated as an unsigned binary integer."
Let's just implement as written in the PoP:

"A subtraction is performed by adding the contents of
 the second operand with the bitwise complement of
 the third operand along with a borrow indication from
 the rightmost bit position of the fourth operand and
 the result is placed in the first operand."

We can reuse gen_ac2_i64().
