        Fixed build failure caused by merge.

        * jit/JITStubs.cpp:
        (JSC::DEFINE_STUB_FUNCTION): On error, return a single value, since this
        function no longer returns a pair.

        Fixed a crash seen on Windows when calling a function with too many
        arguments.
        
        SunSpider reports no change.
        
        No test because the ASSERT I added fires in existing tests.

        * jit/JITStubs.cpp:
        (JSC::DEFINE_STUB_FUNCTION): Make sure to grow the registerFile when too
        many arguments have been provided, since the caller only allocated enough
        registerFile space for the arguments it provided, not enough for the extra
        copy of arguments we're going to need.

        Build fix for JSFunction
        https://bugs.webkit.org/show_bug.cgi?id=39658

        MSVC can't compile one of JSFunction constructors when JIT is disabled.
        "PassRefPtr<NativeExecutable>" causes the compile error as NativeExecutable is not defined. 
        Add ENABLE(JIT) guard to the constructor.

        Bug 39643 - Clean up code generation in the JIT of stub function calls for op_call.

        Presently, as soon as op-call strays off the hot path we set up a set of values on
        the stack to be passed as arguments to cti functions, in case any should be called.

        Instead, hoist the setup of the callframe to happen slightly sooner, and make the
        cti functions to compile & check arity read these values from the callframe. This
        allows up to remove the deprecated methods to manually set up cti arguments, rather
        than using JITStubCall.h.
