ELF Loader: Use physical addresses instead of virtual ones. This works in SE mode because the virtual and physical addresses specified for segments are the same. In Alpha, the LoadAddrMask is still necessary because the virtual and physical addresses are the same and apparently rely on the super page mechanism. All of the regressions pass.
