- Simplify the interference checking code a bit. · 1f582ba6
  Jakob Stoklund Olesen authored Aug 12, 2011
```
This is possible now that we now longer provide an interface to iterate
the interference overlaps.

- Allow loop unrolling to get known trip counts from ScalarEvolution. · 2b6860f0
  Andrew Trick authored Aug 11, 2011
```
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.

- Eliminate the last use of InterferenceResult. · cd14efae
  Jakob Stoklund Olesen authored Aug 11, 2011
```
The Query class now holds two iterators instead of an InterferenceResult
instance. The iterators are used as bookmarks for repeated
collectInterferingVRegs calls.

  Jakob Stoklund Olesen authored Aug 11, 2011

The InterferenceResult iterator turned out to be less important than we
thought it would be.  LiveIntervalUnion clients want higher level
information, like the list of interfering virtual registers.
