This patch fixes the system dependent entries for the half-pixel variance functions in both the RTCD and non-RTCD cases: - The generic C versions of these functions are now correct. Before all three cases called the hv code. - Wire up the ARM functions in RTCD mode - Created stubs for x86 to call the optimized subpixel functions with the correct parameters, rather than falling back to C code.
