Amy Huang 5b3b21f025 [DebugInfo] Fix for adding "returns cxx udt" option to functions in CodeView. ...

Summary:
This change checks for the return type in the frontend and adds a flag
to the DISubroutineType to indicate that the option should be added in
CodeViewDebug.

Previously function types sometimes appeared twice in the PDB: once with
"returns cxx udt" and once without.
