Reviewed by Oliver Hunt and Gavin Barraclough.

This adds typed array get_by_val/put_by_val patching to the baseline JIT. It's
a big (~40%) win on benchmarks that have trouble staying in the DFG JIT. Even
if we fix those benchmarks, this functionality gives us the insurance that we
typically desire with all speculative optimizations: even if we bail to
baseline, we're still reasonably performant.
