This is the first half of Paul's series from last April, reorganized

of AVX decoding.
In most cases this is done by using loops that apply the same code for
all of MMX/SSE/AVX, in some cases AVX needs special-casing for the two
128-bit lanes and then this code is simply missing. The missing helper
code is just 100 lines though, so this _is_ the lion share of the work
to adapt the existing t helpers.
Ok. I'll note that this is a decent intermediate step for
further conversion to tcg/tcg-op-gvec.h, which has a parameter
for the vector length instead of having N functions with the
length implicit in each name.
