Lots of downstream changes in librustc, should be infinitesimally faster.

…arth Add `std_instead_of_core`, `std_instead_of_alloc`, `alloc_instead_of_core` Closes rust-lang#7724 Introduces 3 new lints: - `std_instead_of_core` - lints items resolved through `std` which are available in `core` - `std_instead_of_alloc` - lints items resolved through `std` which are available in `alloc` - `alloc_instead_of_core` - lints items resolved through `alloc` which are available in `core` Though the original issue only mentions `std_instead_of_alloc`, the other two lints could be useful as well. questions: - what do I call the file the lints live in? I was thinking `std_reexports`? changelog: new lint's: [`std_instead_of_core`], [`std_instead_of_alloc`], [`alloc_instead_of_core`]

update AST so that ExprBreak and ExprCont expressions contain names, not idents. Fixes #9047 and makes progress on #6993. Simplifies the compiler very slightly, should make it (infinitesimally) faster.
