impl/ppc/altivec: update to new implementation the signed average function is wrong; it needs to round up the number when only one of them is odd, but that doesn't necessarily seem to be true because altivec is weird, and that's what we need to emulate the quirks for. ugh. also the altivec backend uses the generic functions instead of fallbacks because it does indeed use the exact same memory structure as the generic implementation...
