https://bugs.webkit.org/show_bug.cgi?id=83958

Reviewed by Oliver Hunt.

* bytecode/StructureStubInfo.h:
    - Add fields for the method check info.
* jit/JIT.cpp:
(JSC::PropertyStubCompilationInfo::copyToStubInfo):
    - Store the offsets on the stub info, instead of asserting.
* jit/JIT.h:
    - Delete all the method check related offsets.
* jit/JITPropertyAccess.cpp:
(JSC::JIT::patchMethodCallProto):
    - Use the offset from the stubInfo.
* jit/JITStubs.cpp:
(JSC::DEFINE_STUB_FUNCTION):
    - Pass the stubInfo to patchMethodCallProto.
