Nicer ICE for #67981
Provides a slightly nicer ICE for #67981, documenting the problem. A proper fix will be necessary before `#![feature(unsized_fn_params)]` can be stabilized.
The problem is that the design of the `"rust-call"` ABI is fundamentally not compatible with `unsized_fn_params`. `"rust-call"` functions need to collect their arguments into a tuple, but if the arguments are not `Sized`, said tuple is potentially not even a valid type—and if it is, it requires `alloca` to create.

`IntoFuture::into_future` is no longer unstable
We don't need to gate the `IntoFuture::into_future` call in `.await` lowering anymore.

Sprinkle some `#[inline]` in `rustc_data_structures::tagged_ptr`
This is based on `nm --demangle (rustc +a --print sysroot)/lib/librustc_driver-*.so | rg CopyTaggedPtr` which shows many methods that should probably be inlined. May fix the regression in https://github.com/rust-lang/rust/pull/110795.

Fixes#35785 by converting non UTF-8 linker output to Unicode using the OEM code page.
Before:
```text
= note: Non-UTF-8 output: LINK : fatal error LNK1181: cannot open input file \'m\x84rchenhaft.obj\'\r\n
```
After:
```text
= note: LINK : fatal error LNK1181: cannot open input file 'märchenhaft.obj'
```
The difference is more dramatic if using a non-ascii language pack for Visual Studio.
Currently it creates an `Option` and then does `map`/`unwrap_or` and
`map_or_else` on it, which is hard to read.
This commit simplifies things by moving more code into the two arms of
the if/else.
Validation is neither necessary nor desirable.
The validation is already omitted at mir-opt-level >= 3, so there there
are not changes in MIR test output (the propagation of invalid constants
is covered by an existing test in tests/mir-opt/const_prop/invalid_constant.rs).

Add lint to deny diagnostics composed of static strings
r? ghost
I'm hoping to have a lint that semi-automatically converts simple diagnostics such as `struct_span_err(span, "msg").help("msg").span_note(span2, "msg").emit()` to typed session diagnostics. It's quite hacky and not entirely working because of problems with `x fix` but should hopefully help reduce some of the work.
I'm going to start trying to apply what I can from this, but opening this as a draft in case anyone wants to develop on it.

coverage: Don't underflow column number
I noticed this when running coverage on a debug build of rustc. There
may be other places that do this but I'm just fixing the one I hit.
