FIXME: For some reason, piping straight from llvm-dwp to llvm-dwarfdump doesn't behave well - looks like dwarfdump is reading/closes before dwp has finished.

DWP from non-type-unit debug info for these two translation units:
a.cpp:
  struct foo { };
  foo a;

b.cpp:
  struct bar { };
  void b(bar) {
  }
