> JIT does not include 'this' operand into GC enumeration for synchronized methods on EM64T.
> The cause is spilling of register (this) opnd in "copy expansion" pass and ignoring the
newly created operand in IA32IRManager::calculateLivenessInfo, so usually 'this' opnd is considered
as dead and is not reported to GC.
