In DWARFv5, type units are stored in .debug_info sections, along with compilation units, and they are distinguished by the unit_type field in the header, not by the name of the section. It is impossible to associate the correct index section of a DWP file with the unit before the unit's header is read. This patch fixes reading DWARFv5 type units by parsing the header first and then applying the index entry according to the actual unit type. Differential Revision: https://reviews.llvm.org/D77552
