Duncan P. N. Exon Smith 78141cef2c IR: Augment debug statements for use-list order

Hans Wennborg 82f490c0ba Fix MSVC2012 build error in UseListOrder.cpp 
I think the compiler got confused by the nested DEBUG macros.
It was failing with:

  UseListOrder.cpp(80) : error C2059: syntax error : '}'

Duncan P. N. Exon Smith 20a005f27a Try to fix a layering violation introduced by r213945 
The dragonegg buildbot (and others?) started failing after
r213945/r213946 because `llvm-as` wasn't linking in the bitcode reader.
I think moving the verify functions to the same file as the verify pass
should fix the build.  Adding a command-line option for maintaining
use-list order in assembly as a drive-by to prevent warnings about
unused static functions.

Duncan P. N. Exon Smith 6b6fdc992a IPO: Add use-list-order verifier 
Add a -verify-use-list-order pass, which shuffles use-list order, writes
to bitcode, reads back, and verifies that the (shuffled) order matches.

  - The utility functions live in lib/IR/UseListOrder.cpp.

  - Moved (and renamed) the command-line option to enable writing
    use-lists, so that this pass can return early if the use-list orders
    aren't being serialized.

It's not clear that this pass is the right direction long-term (perhaps
a separate tool instead?), but short-term it's a great way to test the
use-list order prototype.  I've added an XFAIL-ed testcase that I'm
hoping to get working pretty quickly.

This is part of PR5680.
