Description
This is preparation for PPC64 integration: http://openjdk.java.net/jeps/175
This and following ppc64 changes will go into staging repository first and tested there: http://hg.openjdk.java.net/ppc-aix-port/stage/

SAP BiasedLocking implementation departed from the HotSpot dimplementation as
we experimented a lot with it and fixed some issues.  This should not matter
though, as BiasedLocking is forced off in HotSpot code for the C++ interpreter.
