This PR introduces support for lazy deoptimization, which does not construct the DeoptimizedFrame object during a VM operation, instead deferring its construction to the deopt stub.

Lazy deoptimization is not enabled, but can be enabled by changing the option Deoptimizer.Options.UseLazyDeopt. We plan to enable lazy deoptimization at a later time, after confirming that these changes do not cause regressions to eager deoptimization.
