The discriminant check was not working correctly for negative numbers. This change fixes that by masking out the relevant bits correctly.

…rowLii Make the enum check work for negative discriminants The discriminant check was not working correctly for negative numbers. This change fixes that by masking out the relevant bits correctly. Fixes rust-lang#143218.

…r=oli-obk Explicitly handle all nodes in `generics_of` when computing parent If we, for example, forget to feed `generics_of` then it'll silently fall back to empty generics. Make this a bit more explicit.

…eyouxu Add bootstrap check snapshot tests Split off from rust-lang#143048, so that we get a baseline of how check behaved before we make changes to it. Note that the output of the check snapshot tests is suboptimal in many places, as we're missing information about stages and the build compiler. That will be changed in rust-lang#143048. r? `@jieyouxu`

byte-addresses memory -> byte-addressed memory Small typo fix

interpret: move the native call preparation logic into Miri `@nia-e` has to do a bunch of changes to this logic for her native call ptrace work, and it's getting annoying that the logic is split between Miri and rustc. So this moves the logic to Miri, keeping just the generic traversal part in rustc. It is unfortunate that this means we have to expose `get_alloc_raw`/`get_alloc_raw_mut`... I hope the function name is scary enough to reduce the risk of misuse. r? `@oli-obk`

…y789 Use non-global interner in `test_string_interning` in bootstrap Just a small cleanup that we found on our GSoC call. CC `@Shourya742`

… r=oli-obk miri: improve errors for type validity assertion failures Miri has pretty nice errors for type validity violations, printing which field in the type the problem occurs at and so on. However, we don't see these errors when using e.g. `mem::zeroed` as that uses `assert_zero_valid` to bail out before Miri can detect the UB. Similar to what we did with `@saethlin's` UB checks, I think we should disable such language UB checks in Miri so that we can get better error messages. If we go for this we should probably say this in the intrinsic docs as well so that people don't think they can rely on these intrinsics catching anything. Furthermore, I slightly changed `MaybeUninit::assume_init` so that the `.value` field does not show up in error messages any more. `@rust-lang/miri` what do you think?
