commit 974721c66131d208571b8759a1caadf7f995c54c Author: bmeurer <bmeurer@chromium.org> Date: Wed Apr 6 01:37:09 2016 -0700 [generators] Decouple generator resume from fullcodegen. Introduce a ResumeGeneratorTrampoline, which does the actual stack state reconstruction (currently always restores a fullcodegen frame), and introduce appropriate TurboFan builtins for %GeneratorPrototype%.next, %GeneratorPrototype%.return and %GeneratorPrototype%.throw based on this native builtin. Also unify the flooding in case of step-in to always work based on JSFunction and remove the special casing for JSGeneratorObject.
