```
stage2: Drop LLVM's host CPU detection method as fallback

The CPU detection code is nearly at feature parity, we do support
detecting the native CPU on Sparc systems and macos, our ARM/AArch64
model list is quite comprehensive and so is our PPC one.

The only missing pieces are:
- ARM32 detection on Darwin hosts (I don't think anybody is planning on
  running the compiler on a old-ass iPhone)
- s390x detection on Linux hosts, this can be easily added at a later
  stage.

```
