Seems like you don't have a cbranchMODE4 insn in the required mode.
Double check that.  You should only get to that assert if there is no
cbranch pattern.  To assert is indicating that if there is no cbranch
pattern there has to be a cmp pattern.  gcc doesn't have any other
options for a compare-and-branch.
