[X86] AMD Zen 3: same-reg AVX XMM VXORPS is a zero-cycle(!) dep-breaking zero-idiom
Unlike it's legacy SSE XMM XORPS version, which measures as being 1-cycle,
this one is certainly a zero-cycle instruction, in addition to both of them
being dependency breaking.

As confirmed by exegesis measurements, and ref docs.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
