bc733f54c0 reimplement the string pool used for inlined function

5c213dc78c Free DbgScopes in DwarfDebug::endFunction(). Also increased the const-ness of
several fields to make it easier to figure out where bugs might be creeping in.

beginScope and RecordSourceLine.

57578766aa simplify EmitSectionOffset to always use .set if it is
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.
