Reviewed by Michael Saboff.

Source/JavaScriptCore:

Support caching of custom getters and accessors on the prototype chain.
This is relatively trivial and just requires a little work compared to
the direct access mode as we're under more register pressure.

* bytecode/StructureStubInfo.h:
  Removed the unsued initGetByIdProto as it was confusing to still have it present.
* jit/Repatch.cpp:
(JSC::generateProtoChainAccessStub):
(JSC::tryCacheGetByID):
(JSC::tryBuildGetByIDList):

Tools:

Make sure bencher scripts also make noInline exist

* Scripts/bencher:
