Use the newly added DebugInfo (DI) Trivial flag, which indicates if a C++ record is trivial or not, to determine Codeview::FunctionOptions.

Clang and MSVC generate slightly different Codeview for C++ records. For example, here is the C++ code for a class with defaulted ctor,

  class C {
  public:
    C() = default;
  };

Clang will produce a LF for the defaulted ctor while MSVC does not. For more details, refer to FIXMEs in the test cases in "function-options.ll" included with this set of changes.
