[PATCH] D27170: Abstract almost all DwarfDebug out of the classes in DIE.cpp.

[Greg Clayton via Phabricator via llvm-commits]

Address Adrian's comments from email by making DIE just have:

  class DIE {
    const DIEUnit *getUnit() const;
    const DIE *getUnitDie() const;
  };

And skip the "OrNull" variants. Also added a "expected a unit TAG" to the assert in the DIEUnit constructor that checks the incoming dwarf Tag.
