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):
WP_A_Toshiba_3.bit, ff_hevc_put_hevc_uni_w
16 32
before: 2194 3872
after: 2119 3767
WP_B_Toshiba_3.bit, ff_hevc_put_hevc_bi_w

x86: hevc_mc: specify coefficients registers
...
By default, macro EPEL_FILTER loads the coefficients inconditionally
into m14/m15. This forces an unneeded higher register count.
Reduce that count by making them parameters of EPEL_FILTER.
