@uabelho , let me know if the introduction of `isTLIScalarize` prevents the regressions you have seen in your out-of-tree compiler.

Regards,

Francesco


This commits is a rework of the patch in
https://reviews.llvm.org/D67572.

The rework was requested to prevent out-of-tree performance regression
when vectorizing out-of-tree IR intrinsics. The vectorization of such
intrinsics is enquired via the static function `isTLIScalarize`. For
detail see the discussion in https://reviews.llvm.org/D67572.

LLVM LangRef.rst has been updated to describe the syntax of the
`vector-function-abi-variants` attribute.
