Auto merge of #31727 - semarie:openbsd-llvm-cpu, r=alexcrichton

Browse Source 
The initial purpose is to workaround the LLVM bug
https://llvm.org/bugs/show_bug.cgi?id=26554 for OpenBSD.

By default, the `cpu` is defined to `generic`. But with a 64bit
processor, the optimization for `generic` will use invalid asm code as
NOP (the generated code for NOP isn't a NOP).

According to #20777, "x86-64" is the right thing to do for x86_64
builds.

Closes: #31363
