9a26e1320b LoopVectorize fix: LoopInfo must be valid when invoking utils like SCEVExpander. 
In general, one should always complete CFG modifications first, update
CFG-based analyses, like Dominatores and LoopInfo, then generate
instruction sequences.

LoopVectorizer was creating a new loop, calling SCEVExpander to
generate checks, then updating LoopInfo. I just changed the order.

1b6f5a29ab Fix ARM paired GPR COPY lowering 
ARM paired GPR COPY was being lowered to two MOVr without CC. This
patch puts the CC back.

My test is a reduction of the case where I encountered the issue,
64-bit atomics use paired GPRs.

The issue only occurs with selectionDAG, FastISel doesn't encounter it
so I didn't bother calling it.

34ac52d937 Change llvm-ar to use lib/Object. 
This fixes two bugs is lib/Object that the use in llvm-ar found:
* In OS X created archives, the name can be padded with nulls. Strip them.
* In the constructor, remember the first non special member and use that in
  begin_children. This makes sure we skip all special members, not just the
  first one.

The change to llvm-ar itself consist of
* Using lib/Object for reading archives instead of ArchiveReader.cpp.
* Writing the modified archive directly, instead of creating an in memory
  representation.

The old Archive library was way more general than what is needed, as can
be seen by the diffstat of this patch.

Having llvm-ar using lib/Object now opens the way for creating regular symbol
tables for both native objects and bitcode files so that we can use those
archives for LTO.
