More robust comment parsing
fixes#2170
I haven't ported the entire test suite yet. Once we've done that, I will remove the old parsing system (or in fact, turn them into errors so that accidental usage of old-style comments will be detected)
rustup; ptr atomics
Adds support for the operations added in https://github.com/rust-lang/rust/pull/96935.
I made the pointer-binops always return the provenance of the *left* argument; `@thomcc` I hope that is what you intended. I have honestly no idea if it has anything to do with what LLVM does...
I also simplified our pointer comparison code while I was at it -- now that *all* comparison operators support wide pointers, we can unify those branches.
fix comparing wide raw pointers
Fixes https://github.com/rust-lang/rust/issues/96169
However I am not sure if these are the correct semantics. I'll wait for confirmation in that issue.
handle Box with allocators
This is the Miri side of https://github.com/rust-lang/rust/pull/98847.
Thanks `@DrMeepster` for doing most of the work of getting this test case to pass in Miri. :)
add command to run our benchmarks
This is quite ad-hoc but better than nothing IMO.
I have also deleted the old `benches` folder. Some of these tests have UB 😂 and the rest doesn't seem very useful to benchmark the things that are slow about Miri today.

remove ancient tex files
These are the sources of `@solson's` original report, I think. They will remain available in the git history, but I don't think there is much point in still carrying them around on master. The readme links to their rendered PDFs:
