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...
