RFR: JDK-8215166: Remove unused G1PretouchAuxiliaryMemory option

[Evgeny Mandrikov]

Hello!

Please review patch [1] for JDK-8215166 [2]. Also it needs a sponsor since
I have only author status in OpenJDK Census [3].

After this change tier1 tests pass on my machine and I don't find other
occurrences of "G1PretouchAuxiliaryMemory".


With best regards,
Evgeny Mandrikov
