I actually have a while back while trying to improve LDC's 
CodeView output (for the object files, which is then bundled to a 
.pdb by the linker).
For my little dummy example, I get this:

llvm-pdbutil.exe dump --type-stats current.pdb

And `llvm-pdbutil dump --types` does include my little E enum 
with its 3 values, the S struct with its 2 fields...
