bors a7170b0412 Auto merge of #48524 - abonander:check-macro-stability, r=petrochenkov 
check stability of macro invocations

I haven't implemented tests yet but this should be a pretty solid prototype. I think as-implemented it will also stability-check macro invocations in the same crate, dunno if we want that or not.

I don't know if we want this to go through `rustc::middle::stability` or not, considering the information there wouldn't be available at the time of macro expansion (even for external crates, right?).

README.md

NB: This crate is part of the Rust compiler. For an overview of the compiler as a whole, see the README.md file found in librustc.

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.
