1c3424bfc1 Added deny(const_eval_mutable_ptr_in_final_value) attribute to all tests that were expecting the hard error for it. 
I attempted to do this in a manner that preserved the line numbers to reduce the
review effort on the resulting diff, but we still have to deal with the
ramifications of how a future-incompat lint behaves compared to a hard-error (in
terms of its impact on the diagnostic output).

5c786a7fe3 Auto merge of #121516 - RalfJung:platform-intrinsics-begone, r=oli-obk 
remove platform-intrinsics ABI; make SIMD intrinsics be regular intrinsics

`@Amanieu` `@workingjubilee` I don't think there is any reason these need to be "special"? The [original RFC](https://rust-lang.github.io/rfcs/1199-simd-infrastructure.html) indicated eventually making them stable, but I think that is no longer the plan, so seems to me like we can clean this up a bit.

Blocked on https://github.com/rust-lang/stdarch/pull/1538, https://github.com/rust-lang/rust/pull/121542.

4225a1e186 Don't hash lints differently to non-lints. 
`Diagnostic::keys`, which is used for hashing and equating diagnostics,
has a surprising behaviour: it ignores children, but only for lints.
This was added in #88493 to fix some duplicated diagnostics, but it
doesn't seem necessary any more.

This commit removes the special case and only four tests have changed
output, with additional errors. And those additional errors aren't
exact duplicates, they're just similar. For example, in
src/tools/clippy/tests/ui/same_name_method.rs we currently have this
error:
```
error: method's name is the same as an existing method in a trait
  --> $DIR/same_name_method.rs:75:13
   |
LL |             fn foo() {}
   |             ^^^^^^^^^^^
   |
note: existing `foo` defined here
  --> $DIR/same_name_method.rs:79:9
   |
LL |         impl T1 for S {}
   |         ^^^^^^^^^^^^^^^^
```
and with this change we also get this error:
```
error: method's name is the same as an existing method in a trait
  --> $DIR/same_name_method.rs:75:13
   |
LL |             fn foo() {}
   |             ^^^^^^^^^^^
   |
note: existing `foo` defined here
  --> $DIR/same_name_method.rs:81:9
   |
LL |         impl T2 for S {}
   |         ^^^^^^^^^^^^^^^^
```
I think printing this second argument is reasonable, possibly even
preferable to hiding it. And the other cases are similar.

5378c1cf07 Auto merge of #119821 - oli-obk:reveal_all_const_evals, r=lcnr 
Always use RevealAll for const eval queries

implements what is described in https://github.com/rust-lang/rust/pull/116803#discussion_r1364089471

Using `UserFacing` for const eval does not make sense anymore, unless we significantly change things like avoiding revealing opaque types.

New tests are copied from https://github.com/rust-lang/rust/pull/101478

2aac288c18 Use the right level with -Ztreat-err-as-bug. 
Errors in `DiagCtxtInner::emit_diagnostic` are never set to
`Level::Bug`, because the condition never succeeds, because
`self.treat_err_as_bug()` is called *before* the error counts are
incremented.

This commit switches to `self.treat_next_err_as_bug()`, fixing the
problem. This changes the error message output to actually say "internal
compiler error".
