b0cf049a1e 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.

08e747855c Don't assume that external global variables are aligned at their preferred 
alignment. Only the minimum alignment guaranteed by the ABI may be assumed.

87825212a4 More ProfileInfo improvements. 
- Part of optimal static profiling patch sequence by Andreas Neustifter.

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

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

7ded8b7bdf 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).

fcea3a23a0 Restrict LDA to GEPs with the same pointer offset. 
We can not simply apply ZIV testing to the pointer offsets, as this
would incorrectly return independence for e.g. (GEP x,0,i; GEP x,1,-i).

metadata related, which I'm waiting on to avoid conflicting with Devang.
