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/

On platforms where the compiler does not properly support inline
assembly safefetch can be implemented as stub routines. This also
allows to use a single implementation if an architecture is
supported on several os platforms.
