RFR (S): 8147121: Evacuation failure allocation statistics added too late

[Thomas Schatzl]

Hi all,

  can I have reviews for this small change? It moves
printing/recalculation of PLAB statistics to a later point in the GC so
that evacuation failure allocation statistics are added to the current
PLAB statistics instead of the next one.
