This is possible now that we now longer provide an interface to iterate
the interference overlaps.

declaration that never actually gets serialized. Instead, serialize
the various kinds of update records (lexical decls, visible decls, the
addition of an anonymous namespace) for the translation unit, even if
we're not chaining. This way, we won't have to deal with multiple
loaded translation unit declarations.

SCEV unrolling can unroll loops with arbitrary induction variables. It
is a prerequisite for -disable-iv-rewrite performance. It is also
easily handles loops of arbitrary structure including multiple exits
and is generally more robust.

This is under a temporary option to avoid affecting default
behavior for the next couple of weeks. It is needed so that I can
checkin unit tests for updateUnloop.

No test case, sorry. It's one of those bugs where it's really really hard to make one. rdar://9910862.

The Query class now holds two iterators instead of an InterferenceResult
instance. The iterators are used as bookmarks for repeated
collectInterferingVRegs calls.

The current warning in -Wnull-arithmetic for comparisons between NULL and non-pointers is not very helpful.  This patch will update the wording to be more helpful to users.

Old warning:

warning: use of NULL in arithmetic operation [-Wnull-arithmetic]
  return 10 <= NULL;
            ^  ~~~~

New warning:

warning: comparison between NULL and non-pointer ('int' and NULL) [-Wnull-arithmetic]
  return 10 <= NULL;
         ~~ ^  ~~~~

this check based on just the first special type (__builtin_va_list),
but now we have some NULL special type entries to content with.

2) add a couple of CHECK-NOT to guarantee the behavior
3) move to a more appropriate test file
