The patch is a hack which removes use of the MCSymbol::isDefined(...) method, as its use happens to break in the exception JIT context; both in MachineModuleInfo.:: TidyLandingPads(...) and in JITDwarfException:: EmitFrameMoves(...). In this context these symbols are not defined but rather are temporaries.
