• split the "prototype" lookup for hasInstance into opcode stream so it can be cached

~5% speedup on v8 earley-boyer test

• API/JSCallbackObject.h: Add a parameter for the pre-looked-up prototype.
• API/JSCallbackObjectFunctions.h: (JSC::::hasInstance): Ditto.
• API/JSValueRef.cpp: (JSValueIsInstanceOfConstructor): Look up and pass in prototype.
• JavaScriptCore.exp:
• VM/CTI.cpp: (JSC::CTI::privateCompileMainPass): Pass along prototype.
• VM/CodeBlock.cpp: (JSC::CodeBlock::dump): Print third arg.
• VM/CodeGenerator.cpp: (JSC::CodeGenerator::emitInstanceOf): Implement this, now that there is a third argument.
• VM/CodeGenerator.h:
• VM/Machine.cpp: (JSC::Machine::privateExecute): Pass along the prototype. (JSC::Machine::cti_op_instanceof): ditto
• kjs/JSObject.cpp: (JSC::JSObject::hasInstance): Expect to get a pre-looked-up prototype.
• kjs/JSObject.h:
• kjs/nodes.cpp: (JSC::InstanceOfNode::emitCode): Emit a get_by_id of the prototype property and pass that register to instanceof.
• kjs/nodes.h:
