s390x/tcg: Implement VECTOR FP ADD
1. We'll reuse op_vfa() for similar instructions later, prepare for
that.
2. We'll reuse vop64_3() for other instructions later.
3. Take care of modifying the vector register only if no trap happened.
- on traps, flags are not updated and no elements are modified
- traps don't modify the fpc flags
- without traps, all exceptions of all elements are merged
4. We'll reuse check_ieee_exc() later when we need the XxC flag.
We have to check for exceptions after processing each element.
Provide separate handlers for single/all element processing. We'll do
the same for all applicable FP instructions.
