[CodeView] Emit function options for subprogram and member functions
Summary:
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 a 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.
