This revision is now accepted and ready to land.

The change LGTM but the test could just be a unit test instead of doing the 
whole compile->start->attach->expr command cycle.

You can just add this to the `TestClangASTContext.cpp` to test the (nested) 
desugaring and the three types you covered (and one of the switch statements).

  static QualType makeConstInt(clang::ASTContext &ctxt) {
    QualType result(ctxt.IntTy);
    result.addConst();
    return result;
  }
  
  TEST_F(TestClangASTContext, TestGetTypeClassDeclType) {
    clang::ASTContext &ctxt = *m_ast->getASTContext();
    auto *nullptr_expr = new (ctxt) CXXNullPtrLiteralExpr(ctxt.NullPtrTy, 
SourceLocation());
    QualType t = ctxt.getDecltypeType(nullptr_expr, makeConstInt(ctxt));
    EXPECT_EQ(lldb::eTypeClassBuiltin, m_ast->GetTypeClass(t.getAsOpaquePtr()));
  }
  
  TEST_F(TestClangASTContext, TestGetTypeClassTypeOf) {
    clang::ASTContext &ctxt = *m_ast->getASTContext();
    QualType t = ctxt.getTypeOfType(makeConstInt(ctxt));
    EXPECT_EQ(lldb::eTypeClassBuiltin, m_ast->GetTypeClass(t.getAsOpaquePtr()));
  }
  
  TEST_F(TestClangASTContext, TestGetTypeClassTypeOfExpr) {
    clang::ASTContext &ctxt = *m_ast->getASTContext();
    auto *nullptr_expr = new (ctxt) CXXNullPtrLiteralExpr(ctxt.NullPtrTy, 
SourceLocation());
    QualType t = ctxt.getTypeOfExprType(nullptr_expr);
    EXPECT_EQ(lldb::eTypeClassBuiltin, m_ast->GetTypeClass(t.getAsOpaquePtr()));
  }
  
  TEST_F(TestClangASTContext, TestGetTypeClassNested) {
    clang::ASTContext &ctxt = *m_ast->getASTContext();
    QualType t_base = ctxt.getTypeOfType(makeConstInt(ctxt));
    QualType t = ctxt.getTypeOfType(t_base);
    EXPECT_EQ(lldb::eTypeClassBuiltin, m_ast->GetTypeClass(t.getAsOpaquePtr()));
  }
