RFR: 8365956: GenShen: Adaptive tenuring threshold algorithm may raise threshold prematurely [v5]

[William Kemper]

> The adaptive tenuring algorithm has been modified to begin its evaluation of mortality rates from the current tenuring threshold. To compliment this change, objects must also now be strictly above the tenuring threshold to be promoted (instead of greater-than-or-equal).
