Add flag --deoptimize-alot, which will lazily deoptimize all live optimized frames. Currently only the presence of deoptimization information is checked. Add kDeoptAfter deoptimization point, which is the continuation for lazy deoptimization, after a call. Rename kDeopt to kDeoptBefore. Removed a tests case that called into a native without properly setting up a Dart frame (Ok-d by Siva). Native functions are not optimizable. TODO: Split deoptimization information from DeoptimizationStubs. Check for redundant PcDescriptor information (what can be merged, especially at calls).
