x86inc: activate REP_RET automatically
Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition.
REP_RET is still needed manually when it's a branch target, but that's much rarer.
The implementation involves lots of spurious labels, but that's ok because we strip them.
