            Bug ID: 163224
           Summary: [DOMJIT] DOMJIT::Patchpoint should have a way to
                    receive constant folded arguments
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

DOMJIT::Patchpoint for CallDOM takes JSGlobalObject to use it when creating wrapper object.
Currently, DOMJIT::Patchpoint always receives it as GPRReg. However, sometimes, we can get a constant value for that (I'm now assuming `document.getElementById("...")`)
In that case, we can emit more efficient code since we can drop some of checks ("World is normal" check).
