398f531915 x86: hevc_mc: fewer xmm regs used in epel h/v 
11 xmm regs seem only required for avx2.

89cb4995fa x86: hevc_mc: save 1 gpr in epel filter loading 
The 3*stride value stored in r3src can be loaded much later,
so use r3src instead of a dedicated gpr when possible.

0810608e23 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):

f1793fe9cd 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.
