21a0451167 vp9: split decode_coeff_b loop inside txsz branch. 
The advantage of this is that the is32x32 division branch in
decode_coeffs_b is removed from the inner loop to outside the block
coef decoding loop in decode_coeffs. Also, it allows us to merge the
txsz branches from the block coef decoding loop, the context merge
and the context split.

fdb093c4e4 vp9/x86: intra prediction SIMD. 
Partially based on h264_intrapred. (I hope to eventually merge these
two intrapred implementations back together.)

91126dc481 flacdsp_lpc_template: add comment to explain the CONFIG_SMALL code 
I found the optimisation of 2 samples per iteration obscured the
underlying algorithm.  I had to write it out on paper and translate into
a mathematical sum to see that the two samples are unconnected.  I hope
that if anyone else is struggling to understand the code that this will
be useful.
