This has failed because we don't have common prefixes anymore, you'll need to adjust the top of the file to be something like:
```
; RUN: llc < %s -mtriple=i686-unknown-unknown -mattr=+avx512f | FileCheck %s --check-prefixes=AVX-32,AVX512F-32
; RUN: llc < %s -mtriple=x86_64-unknown-unknown -mattr=+avx512f | FileCheck %s --check-prefixes=AVX-64,AVX512F-64
; RUN: llc < %s -mtriple=i686-unknown-unknown -mattr=+avx512f,+avx512bw | FileCheck %s --check-prefixes=AVX-32,AVX512BW-32
; RUN: llc < %s -mtriple=x86_64-unknown-unknown -mattr=+avx512f,+avx512bw | FileCheck %s --check-prefixes=AVX-64,AVX512BW-64
