 From an on-disk storage perspective, Clang modules are precompiled
 header files that contain serialized Clang ASTs of all the
 declarations found in a Clang module. In traditional DWARF debug info,
 two object files that were built from sources that imported the same
 header file will both contain DWARF debug type info for types in that
 header file. This can lead to a lot of redundant `debug
