use funnel shift as fallback impl for rotating shifts That lets us remove this gnarly implementation from Miri and const-eval. However, `rotate_left`/`rotate_right` are stable as const fn, so to do this we have to `rustc_allow_const_fn_unstable` a bunch of const trait stuff. Is that a bad idea? Cc `@oli-obk` `@fee1-dead` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
