[LLVMdev] Updating value from PHI
I have attached a case of what I am trying to do, I'm pretty sure I'm just
missing some simple API call. In the cfg you can see that although Im
setting "lsr.iv441" as "lsr.iv44" from for.body.387.i it's not propagating
that through the block or graph.

[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;
