Bill Currie 23613ca985 [simd] Get the new functions working on older hardware
In some cases, gcc-11 does a good enough job translating normal looking
C expressions so use just those, but other times need to dig around for
an appropriate intrinsic.

Also, now need to disable psapi warnings when compiling for anything
less than avx.
