Summary: If we have symbol information in a separate file, we need to be very careful about presenting a unified section view of module to the rest of the debugger. ObjectFileELF had code to handle that, but it was being overly cautious -- the section->GetFileSize()!=0 meant that the unification would fail for sections which do not occupy any space in the object file (e.g., .bss). In my case, that manifested itself as not being able to display the values of .bss variables properly as the section associated with the variable did not have it's load address set (because it was not present in the unified section list). I test this by making sure the unified section list and the variables refer to the same section.
