[SLPVectorizer][X86] Remove unused check-prefixes
Hi @RKSimon, did you mean to remove _all_ the prefixes here?
For trunk yes - thats whats needed after D90281 for FileCheck to run with -allow-unused-prefixes=false (which will be the new default soon).
For D90445 I think you will just need to add back --check-prefixes=CHECK,SSE and --check-prefixes=CHECK,AVX (and a bit more for pr47629.ll
I see, thanks.
