            Bug ID: 186446
           Summary: jumpTrueOrFalse only takes the fast path for boolean
                    false
           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: tzagallo at apple.com

jumpTrueOrFalse did a mask check to take the fast path for boolean literals, but it would only work for false. Change it so that it takes the fast path for true, false and undefined.
