Rustc_codegen_cranelift is an alternative codegen backend for rustc based on Cranelift. It has the potential to improve compilation times in debug mode. In my experience the compile time improvements over debug mode LLVM for a clean build are about 20-30% in most cases.

This PR adds cg_clif as optional codegen backend. By default it is only enabled for ./x.py check. It can be enabled for ./x.py build too by adding cranelift to the rust.codegen-backends array in config.toml.

I think this has broken -Cpasses=list, which is now empty, as well as the LLVM version output in rustc -Vv, which is now missing

Oops. I used cfg!(llvm) instead of cfg!(feature = "llvm") for those.
