Continue to simplify the `DIDescriptor` subclasses, so that they behave more like raw pointers. Remove `getRaw()`, replace it with an overloaded `get()`, and overload the arrow and cast operators. Two testcases started to crash on the arrow operators with this change because of `scope:` references that weren't real scopes. I fixed them. Soon I'll add verifier checks for them too. This also adds explicit dereference operators. Previously, the builtin dereference against `operator MDNode *()` would have worked, but now the builtins are ambiguous. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233030 91177308-0d34-0410-b5e6-96231b3b80d8
