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.

7fafbde038 Auto merge of #2275 - RalfJung:permissive-provenance-for-all, r=RalfJung 
Enable permissive provenance by default

This completes the plan laid out in https://github.com/rust-lang/miri/issues/2133:
- We use permissive provenance with wildcard pointers by default.
- We print a warning on int2ptr casts. `-Zmiri-permissive-provenance` suppresses the warning; `-Zmiri-strict-provenance` turns it into a hard error.
- Raw pointer tagging is now always enabled, so we remove the `-Zmiri-tag-raw-pointers` flag and the code for untagged pointers. (Passing the flag still works, for compatibility -- but we just ignore it, with a warning.)

We also fix an intptrcast issue:
- Only live allocations are considered when computing the AllocId from an address.

So, finally, Miri has a good story for ptr2int2ptr roundtrips *and* no weird false negatives when doing raw pointer stuff with Stacked Borrows. :-) 🎉   Thanks a lot to everyone who helped with this, in particular `@carbotaniuman` who convinced me this is even possible.

ab88ba4299 Auto merge of #2270 - RalfJung:futex-ordering, r=RalfJung 
test that futexes induce appropriate synchronization

This fails when I remove the `validate_lock_acquire` or `validate_lock_release` from `futex_wake`. So finally we got those code paths actually covered in tests. :)
