[11u] RFR 8251118: BiasedLocking::preserve_marks should not have a HandleMark

[Aleksey Shipilev]

Original bug:
   https://bugs.openjdk.java.net/browse/JDK-8251118
   https://hg.openjdk.java.net/jdk/jdk/rev/abb125b87e74

This is a follow-up for JDK-8249192. The change is trivial, but it needs some adjustments in the 
test code: the test package was not introduced yet, so "gc." needs to be dropped.

11u patch:
