Sync rustc_codegen_cranelift

I did a large refactoring of the intrinsics module to remove the intrinsic_match macro which is not very clear to other people. This also enables rustfmt to run on this code. While I already did a sync yesterday, I am going to do another sync again to avoid potential conflicts as those will likely be painful to resolve.
