[llvm-dev] X86 backend code ownership

+1 - especially since I think Craig convinced Intel that LLVM isn't just a
hobby project for him. :)

inconsistency in instruction selection behavior between the older AVX

fix cases where concepts haven't been extended to wider vectors yet. For
instance, the instcombine handling of x86 shift intrinsics. I've also been
trying to remove AVX512 intrinsics for things that can be represented with
native IR or where we can use a legacy instrinsic and only need a masking IR
select instruction to support AVX512.

Several people replied to the email with +1s. Quentin had some concerns.
