on platforms with relocations in debug info and also temporarily
revert r191800 due to conflicts with the revert of r191792.

and it is shared across CUs.
We add a few maps in DwarfDebug to map MDNodes for the type system to the
corresponding DIEs: MDTypeNodeToDieMap, MDSPNodeToDieMap, and
MDStaticMemberNodeToDieMap. These DIEs can be shared across CUs, that is why we
keep the maps in DwarfDebug instead of CompileUnit.
Sometimes, when we try to add an attribute to a DIE, the DIE is not yet added
to its owner yet, so we don't know whether we should use ref_addr or ref4.
We create a worklist that will be processed during finalization to add
attributes with the correct form (ref_addr or ref4).
We add addDIEEntry to DwarfDebug to be a wrapper around DIE->addValue. It checks
whether we know the correct form, if not, we update the worklist
(DIEEntryWorklist).
A testing case is added to show that we only create a single DIE for a type
MDNode and we use ref_addr to refer to the type DIE.

In DIBuilder, the context field of a TAG_member is updated to use the
scope reference. Verifier is updated accordingly.
DebugInfoFinder now needs to generate a type identifier map to have
access to the actual scope. Same applies for BreakpointPrinter.
processModule of DebugInfoFinder is called during initialization phase
of the verifier to make sure the type identifier map is constructed early
enough.
We are now able to unique a simple class as demonstrated by the added
testing case.
