DebugInfo: Remove dead code from old DebugLoc API

Remove old API for `DebugLoc` now that all the callers have been
updated.  If this broke your out-of-tree build, here's a quick map from
the old API to the new one:

    DebugLoc DebugLoc::getFromMDLocation(MDNode *)
      => DebugLoc::DebugLoc(MDLocation *)
      => explicit DebugLoc::DebugLoc(MDNode *) // works with broken code

    MDNode *DebugLoc::getAsMDNode(LLVMContext &)
      => MDLocation *DebugLoc::get()
      => DebugLoc::operator MDLocation *()
      => MDNode *DebugLoc::getAsMDNode() // works with broken code

    bool DebugLoc::isUnknown()
      => DebugLoc::operator MDLocation *()
          i.e.: if (MDLocation *DL = ...)
      => DebugLoc::operator bool() // works with broken code
          i.e.: if (DebugLoc DL = ...)

    void DebugLoc::getScopeAndInlinedAt(MDNode *&, MDNode *&)
      => use: MDNode *DebugLoc::getScope()
         and: MDLocation *DebugLoc::getInlinedAt()

    MDNode *DebugLoc::getScopeNode(LLVMContext &)
      => MDNode *DebugLoc::getInlinedAtScope()

    void DebugLoc::dump(LLVMContext &)
      => void DebugLoc::dump()

    void DebugLoc::getFnDebugLoc(LLVMContext &)
      => void DebugLoc::getFnDebugLoc()

    MDNode *DebugLoc::getScope(LLVMContext &)
      => MDNode *DebugLoc::getScope()

    MDNode *DebugLoc::getInlinedAt(LLVMContext &)
      => MDLocation *DebugLoc::getInlinedAt()

I've noted above the only functions that won't crash on broken code (due
to downcasting to `MDLocation`).  If your code could be dealing with
broken IR (i.e., you haven't run the verifier yet, or you've used a
temporary node that will eventually (but not yet) get RAUW'ed to an
`MDLocation`), you need to restrict yourself to those.

Summary:
The 'R' constraint is actually supposed to be much more complicated than
this and is defined in terms of whether it will cause macro expansion in
the assembler. 'R' is getting less useful due to architecture changes and
