JSC bytecode contains a method_check opcode that is used to optimize method calls of the form o.foo(...). The DFG JIT currently does not support this opcode at all, so JS functions that contain method calls cannot be compiled with DFG. The DFG JIT should support both the method_check opcode and the optimizations associated with it.
