    M llvm/test/Transforms/LoopUnroll/peel-loop-phi-analysis.ll

  Log Message:
  -----------
  Expand loop peeling phi computation to handle binary ops and casts

Summary:
Expand the capabilities of the code for computing how many peels are
needed to make phis determined.  A cast gets the peel count for the
value being casted while a binary op gets the maximum of the operands.

Respond to review comments: remove redundant asserts.
