[LLVMdev] Updating value from PHI

A good example of how to use it -- one that sounds very similar to what
you're doing -- can be found in Transforms/Scalar/LoopRotation.cpp

[LLVMdev] Updating value from PHI
I am splitting a one BB loop into two BB.
Basically, the one loop BB has 3 incoming values, one form back edge two
from other edges. I want to extract the PHIs from the other two edges out
into it's own BB and delete that from the loop, then redirect the backedge
to the loopbody (non extracted portion) and create a new PHI coming from
the extracted BB and the backedge.
I can do this;
