Summary:
This merges VFPtrInfo and VBTableInfo into VPtrInfo, since they hold
almost the same information.  With that change, the vbtable mangling
code can easily be applied to vftable data and we magically get the
correct, unambiguous vftable names.

Fixes PR17748.

This reverts commit r202420, which broke the build.

This cleans up some constructors that would not be safe once FileEntry
owns the storage for its name. These were already suspect, since they
wouldn't work if the FileEntry had an open file descriptor. The only
user for these constructors was in UniqueFileContainer, which wasn't a
very useful abstraction anyway. So it and UniqueDirContainer have been
replaced with std::map<UniqueID, *>.

This change should not affect anything outside the FileManager.

In llvm the only semantic difference between internal and private is that llvm
tries to hide private globals my mangling them with a private prefix. Since
the globals changed by this patch already had the magic don't mangle marker,
there should be no change in the generated assembly.

A followup patch should then be able to drop the \01L and \01l prefixes and let
llvm mangle as appropriate.

Some MC components like Target Streamers or Assembly Parsers

If a function returns a large struct by value return the first 4 words
in registers and the rest on the stack in a location reserved by the
caller. This is needed to support the xC language which supports
functions returning an arbitrary number of return values. This is
r202397 reapplied with a fix to avoid an uninitialized read of a member.

This is a small bit of refactoring in preparation for FileEntry owning

We moved MCJIT to use native object formats a long time ago and R600
