bdff548e4d eliminate the "Value" printing methods that print to a std::ostream. 
This required converting a bunch of stuff off DOUT and other cleanups.

c40f17b087 Generalize ScalarEvolution to be able to analyze GEPs when 
TargetData is not present. It still uses TargetData when available.
This generalization also fixed some limitations in the TargetData
case; the attached testcase covers this.

   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.

699db99c1a SIV/MIV classification for LDA. 
LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of
depth N and a compound SCEV of M atomic SCEVs. As both N and M will
typically be very small, this should not be a problem. If it turns out
to be one, rewriting getLoops as SCEVVisitor will reduce complexity to
O(M).

fef8bb24de Instead of eagerly creating new SCEVs to replace all SCEVs that are 
affected after a PHI node has been analyzed, just remove affected
SCEVs from the Scalars map, so that they'll be (lazily) recreated as
needed. This avoids creating SCEV objects that aren't actually needed.

Also, rewrite the associated def-use walking code to be non-recursive
and to continue traversing past Instructions that don't have an
entry in the Scalars map.
