These debug checks make it a pain to read machine code generated by Ion in debug builds.
It's nicer to not emit this until bailAfter is called for the first time, at that point we can release JIT code to force a recompile with the instrumentation on.

This mechanism added a lot of machine code to Ion JIT code, making it hard to analyze
codegen. With this change we only emit this when necessary.
