  1. rustc: move pretty printing into its own module. 

    There's a lot of it, and it's a fairly well-defined/separate chunk of
code, so it might as well be separate.

  2. rustc: remove a trait that is unnecessary after pretty move. 

    The type in the `impl` is now in the module with the trait.

  1. rustc: implement a pretty mode to print ident/name's ctxt & gensyms. 

    `--pretty expanded,hygiene` is helpful with debugging macro issues,
since two identifiers/names can be textually the same, but different
internally (resulting in weird "undefined variable" errors).
