[PATCH] x86: don't use VexWIG in SSE2AVX templates

[Jan Beulich <jbeulich@suse.com>]

Several years ago it was decided that SSE2AVX templates should not be
sensitive to -mvexwig= (upon my suggestion to consistently make all
sensitive as long as they don't require a specific setting of VEX.W).
Adjust the four that still are, switching to use of Vex128 at the same
time.

I'm certainly amenable to using VexW0 in the 2nd extractps entry; I've
picked VexW1 because that's more in line with what the user has actually
requested (hence also the minor testsuite adjustments).
