one loop is involved in the increment of an addrec for another
loop. This fixes rdar://8168938.

Pull out r108755.  After offline discussion with Chris, we're going to go a different direction with this.

This is a work in progress. So far we have some basic loop analysis to help
determine where it is useful to split a live range around a loop.

The actual loop splitting code from Splitter.cpp is also going to move in here.

Also fix access of private member type by << operator.

- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

Speculatively revert r108813, in an attempt to get the self-host buildbots working again.  I don't see why this patch
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

Updated renderer to use allocation information from VirtRegMap (if
available) to render spilled intervals differently.

breaking teh everything.

Separate PassInfo into two classes: a constructor-free superclass (StaticPassInfo) and a constructor-ful subclass (PassInfo).

loop, for the reasons in the comments.  This is a
major win on 253.perlbmk on ARM Darwin.  I expect it
to be a good heuristic in general, but it's possible
some things will regress; I'll be watching.
