Summary: It possible that a single module has indexed and non-indexed compile units. In this case, we can use the fast indexed lookup for the first ones and fall back to the manual index for the others. This patch implements this functionality by adding a units_to_avoid argument to the ManualDWARFIndex constructor. Any units present in that list will be ignored for the purposes of manual index. Individual DebugNamesDWARFIndex then always consult both the manual fallback index as well as the index in the .debug_names section.
