ability to see the remainder), but the only user was the unit tests.  If

Seems at some point the intent was to emit fission ranges_base as unique

section for all CUs being compiled and all the ranges_base relative
addresses are relative to that. So removing this dead code and leaving

faster if it has distinct ranges for each CU).
