Davide Italiano 383c55870e [LoopIdiomRecognize] Transform backedge-taken count check into an assertion. ...

runOnCountable() allowed the caller to call on a loop without a
predictable backedge-taken count. Change the code so that only loops
with computable backdge-count can call this function, in order to catch
abuses.
