Hold a queue of iterator ranges (not operations) in wouldOpBeTriviallyDead (#123642)
Ranges let us push the whole blocks onto the queue in constant time. If
one of the first ops in the block is side-effecting we'll be able to
provide the answer quickly. The previous implementation had to walk the
block and queue all the operations only to start traversing them again,
which was a considerable slowdown for compile times of large MLIR
programs in our benchmarks.
