Summary TestWithModuleDebugging fails since llvm r308708

This commit added skeleton compile unit to the generated module. This extra compile unit confuses lldb's dwarf parsing logic, because it thinks this is a DWO compile unit. However, the rest of the module contains regular compile units. Since we have a DWO compile unit at offset zero, the DIE queries get forwarded to the compile units in the pch module, even though the regular dwarf behavior would be to first look up the compile unit based on the die offset alone, and then fetch the DIE from that unit. I'm not really sure what would be the best fix for this situation.
