          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2

        ReportedBy: fpizlo at apple.com


This is starting to be essential because of the need to optimize create_arguments, create_activation, among others. The point is that if these opcodes appear on paths that dominate the exit, then we should hoist them and have them execute unconditionally.
