- [rustc now avoids unnecessary copies of arguments that are
simple bindings][45380] This should improve memory usage on average by 5-10%.
- [Updated musl used to build musl rustc to 1.1.17][45393]
-- [Refactored type memory layouts and ABIs.][45225] This will reduce
- memory size for some types. Eg. `io::Result<()>` is now 16 bytes
- where it was previously 24.
