This is the first half of Paul's series from last April, reorganized to have no occurrence of YMM_ONLY or SHIFT == 2---meaning it can be committed without much fuss, even without a plan for the implementation of AVX decoding.
In most cases this is done by using loops that apply the same code for all of MMX/SSE/AVX, and in fact this series removes basically all uses of XMM_ONLY in the code. 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 only 10 lines though, so this _is_ the lion share of the work to adapt the existing helpers. The full work, with the AVX parts rebased on top of these, is at branch i386-avx of https://gitlab.com/bonzini/qemu. The branch passes the tests that Paul had posted, while this reduced part passes the reduced SSE version.
