Sync rustc_codegen_cranelift

For cg_clif itself there have been a couple of bug fixes since the last sync, a Cranelift update and implemented all remaining simd platform intrinsics used by `std::simd`. (`std::arch` still misses a lot though) Most of the diff is from reworking of the cg_clif build system though.

r? `@ghost`
