[lldb/DWARF] Search fallback to the manual index in GetFullyQualified… (
llvm#102123) …Type This is needed to ensure we find a type if its definition is in a CU that wasn't indexed. This can happen if the definition is in some precompiled code (e.g. the c++ standard library) which was built with different flags than the rest of the binary.
