While the new BBQ baseline JIT supports entry tier-up checks, we don't currently support tiering up in the middle of loops. This significantly affects our score on JetStream 3, for example on the gcc-loops benchmark, because we end up stuck in the LLInt or BBQ and unable to tier up to BBQ or OMG respectively.
