ComboBox within the menu does not work properly.
Temporarily use the deprecated menu instead.

Improve local branch relocation handling

Reworks the local-branch handling logic to be more
unified: scan_instructions does all the work up front,
and process_instruction / display_instruction can
simply use the calculated branch destination instead
of performing their own is-relocation-target-
function-local checks.

(Hopefully) Fixes encounter#192
