[PATCH 00/18] target/i386: make most SSE helpers generic in the vector size |

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, 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.
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 SSE
version that I have sent earlier today.
