cmd/internal: allow ADDE to work with memory location on s390x
Originally on s390x, ADDE does not work when adding numbers from a memory location.
For example: ADDE (R3), R4 will result in a failure.
Since ADDC, ADD and ADDW already supports adding from memory location,
let's support that for ADDE as well.
