vpx/vpx_dsp/mips/vpx_convolve8_horiz_msa.c
Zoe Liu 7186a2dd86 Code refactor on InterpKernel 
It in essence refactors the code for both the interpolation
filtering and the convolution. This change includes the moving
of all the files as well as the changing of the code from vp9_
prefix to vpx_ prefix accordingly, for underneath architectures:
(1) x86;
(2) arm/neon; and
(3) mips/msa.
The work on mips/drsp2 will be done in a separate change list.
