This function doesn't have an obvious home, but there's little reason for it to be in mir-transform, and having it in `rustc_driver_impl::pretty` at least puts it near other callers of `write_mir_pretty`.
The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
