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.

again.
