Rust frontend patches v2

[Philip Herron]

Hi everyone

I noticed a few patches still didn't make it through here with the
400kb limit. In the meantime, Mark pointed out to me that they can all
be viewed over here:

https://inbox.sourceware.org/gcc-patches/20220824115956.737931-9-philip.herron@embecosm.com/T/#rbff0bb3df2780fecd9ee3d2baa864d9140d24b54

The missing patches on
https://gcc.gnu.org/pipermail/gcc-patches/2022-August/thread.html#600200
are 8, 10, 13, 29, and 22.

Thanks let me know if there is anything more I can do to help.
