Prepare proc_macro for decoupling it from the rest of the compiler. This is #49219 up to the point where the bridge is introduced. Aside from moving some code around, the largest change is the rewrite of `proc_macro::quote` to be simpler and do less introspection. I'd like to also extend `quote!` with `${stmt;...;expr}` instead of just `$variable` (and maybe even `$(... $iter ...)*`), which seems pretty straight-forward now, but I don't know if/when I should. r? @alexcrichton or @dtolnay cc @jseyfried @petrochenkov |

The syntax crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
For more information about how these things work in rustc, see the rustc guide:
