c2a4574760 7143664: Clean up OrderAccess implementations and usage 
Clarify and correct the abstract model for memory barriers provided by the orderAccess class. Refactor the implementations using template specialization to allow the bulk of the code to be shared, with platform specific customizations applied as needed.

Implementation of the CAS primitive for x64 compressed oops was incorrect. It kills rscratch2 register (r11), which is allocatable in C1. Also, we don't need to restore cmpval as it's never used after that, so we need only one temporary register, which can be scratch1.
