Add `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` lint cc #79813 This PR adds an allow-by-default future-compatibility lint `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS`. It fires when a trailing semicolon in a macro body is ignored due to the macro being used in expression position: ```rust macro_rules! foo { () => { true; // WARN } } fn main() { let val = match true { true => false, _ => foo!() }; } ``` The lint takes its level from the macro call site, and can be allowed for a particular macro by adding `#[allow(semicolon_in_expressions_from_macros)]`. The lint is set to warn for all internal rustc crates (when being built by a stage1 compiler). After the next beta bump, we can enable the lint for the bootstrap compiler as well.

Update `smallvec` to 1.8.1. This pulls in https://github.com/servo/rust-smallvec/pull/282, which gives some small wins for rustc.

proc_macro: use crossbeam channels for the proc_macro cross-thread bridge This is done by having the crossbeam dependency inserted into the proc_macro server code from the server side, to avoid adding a dependency to proc_macro. In addition, this introduces a -Z command-line option which will switch rustc to run proc-macros using this cross-thread executor. With the changes to the bridge in #98186, #98187, #98188 and #98189, the performance of the executor should be much closer to same-thread execution. In local testing, the crossbeam executor was substantially more performant than either of the two existing CrossThread strategies, so they have been removed to keep things simple.
