Auto merge of #85332 - RalfJung:ptr-in-str, r=oli-obk
CTFE validation: handle pointers in str I also finally learned how I can match *some* NOTEs in a ui test without matching all of them, and applied that to some const tests in the 2nd commit where I added NOTE because I did not know what I was doing. I can separate this into its own PR if you prefer. Fixes https://github.com/rust-lang/rust/issues/83182 r? `@oli-obk`
