I noticed that several of the List functions do simple linear searches that
can be optimized with SIMD intrinsics (as was done for XidInMVCCSnapshot in
37a6e5d). The following table shows the time spent iterating over a list
of n elements (via list_member_int) one billion times on my x86 laptop.

In this particular case, we use

Many thanks for the updated patch.
Despite the fact that the patch is still work in progress all in all
