x86: hevc_mc: better register allocation

The xmm reg count was incorrect, and manual loading of the gprs
furthermore allows to noticeable reduce the number needed.
The modified functions are used in weighted prediction, so only a
few samples like WP_* exhibit a change. For this one and Win64
(some widths removed because of too few occurrences):
