0b9a237b23 hevc: Add NEON 4x4 and 8x8 IDCT 
Optimized by Martin Storsjö <martin@martin.st>.

The speedup vs C code is around 3.2-4.4x.

688417399c hevcdsp: split the pred functions by width 
This should allow for more efficient SIMD.

1f821750f0 hevcdsp: split the qpel functions by width instead of by the subpixel fraction 
This should allow for more efficient SIMD.

Keep the C versions as they are now, to allow the compiler to inline the
interpolation coefficients.

d8ebb6157d hevcdsp: fix a function name

weighting there.
