[turbofan] Implement %_NewObject using FastNewObjectStub. The inline allocation sequence in the optimizing compilers cannot deal well with funky types like JSRegExp, which have some magic fields in addition to the inobject properties. In Crankshaft we already use the FastNewObjectStub for %_NewObject in general, so fix TurboFan to the same. Hopefully one day we can kill %_NewObject completely.

[flags] Rename --opt to --turbofan To be consistent with the all the other tiers and avoid confusion, we rename --opt to ---turbofan, and --always-opt to --always-turbofan.
