Decouple `rustc_hir::print` into `rustc_hir_pretty` #70344

Centril · 2020-03-24T02:43:38Z

High level summary:

The HIR pretty printer, rustc_hir::print is moved into a new crate rustc_hir_pretty.
rustc_ast_pretty and rustc_errors are dropped as rustc_hir dependencies.
The dependence on HIR pretty is generally reduced, leaving rustc_save_analysis, rustdoc, rustc_metadata, and rustc_driver as the remaining clients.

The main goal here is to reduce rustc_hir's dependencies and its size such that it can start and finish earlier, thereby working towards #65031.

The printing stuff isn't quite my wheelhouse.

I wonder if this was always meant to print a Ty but accidentally printed HIR.

This also looks like it might be meant to be a Ty not HIR.

Yea I wasn't really satisfied with the current name, yours is better.

r=me after addressing #70344 (comment), the hir::FnRetTy -> Ty stuff is probably too messy.
