Migrate `pgo-gen-lto` `run-make` test to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
This one is so easy, I'm surprised I missed it.

Don't arbitrarily choose one upper bound for hidden captured region error message
You could argue that the error message is objectively worse, even though it's more accurate. I guess we could also add a note explaining like "cannot capture the intersection of two regions" or something, though I'm not sure if that is confusing due to being totally technical jargon.
This addresses the fact that #128752 says "add `+ 'b`" even though it does nothing to fix the issue. It doesn't fix the issue's root cause, though.

bootstrap: clear miri's ui test deps when rustc changes
`@onur-ozkan` I hope this makes sense... it's quite hard to test this, but it did at least cause one rebuild of the right files for me, and then it doesn't seem to keep rebuilding, so at first sight this look at least better than the status quo.
Enable msvc for run-make/rust-lld
This is simply a matter of using the right argument for lld-link.
As a bonus, I also fixed a typo.

error[E0790]: cannot call associated function on trait without specifying the corresponding `impl` type
--> $DIR/E0283.rs:30:21
|
LL | fn create() -> u32;
| ------------------- `Coroutine::create` defined here
...
LL | let cont: u32 = Coroutine::create();
| ^^^^^^^^^^^^^^^^^^^ cannot call associated function of trait
|
help: use a fully-qualified path to a specific available implementation
|
LL | let cont: u32 = <Impl as Coroutine>::create();
| ++++++++ +
LL | let cont: u32 = <AnotherImpl as Coroutine>::create();
| +++++++++++++++ +
```
minor `effects` cleanups
* remove the fixme comment about not needing defaults because it turns out we do need defaults (if I made it None instead it would ice a bunch of tests)
* remove the part that special cased trait args when lowering them. This is now historical because effects doesn't add host args to traits anymore (we use associated types now)
Make create_dll_import_lib easier to implement
This will make it easier to implement raw-dylib support in cg_clif and cg_gcc. This PR doesn't yet include an create_dll_import_lib implementation for cg_clif as I need to correctly implement dllimport in cg_clif first before raw-dylib can work at all with cg_clif.
Required for https://github.com/rust-lang/rustc_codegen_cranelift/issues/1345
We can replace some tricky iterator-mutation code with a much simpler version
that uses `while let` to shrink a slice.
We also check whether a subpattern would be a wildcard _before_ hoisting it,
which will be very useful when trying to get rid of `print::PatKind` later.
Migrate `cross-lang-lto-upstream-rlibs`, `long-linker-command-lines` and `long-linker-command-lines-cmd-exe` `run-make` tests to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
The `long-linker` tests are certainly doing something... interesting - they summon `rustc` calls with obscene quantities of arguments and check that this is appropriately handled. I removed the `RUSTC_ORIGINAL` magic - it's equivalent to `RUSTC` in `tools.mk`, so what is the purpose? Making it so the massive pile of flags doesn't modify rustc itself and start leaking into other tests? Tell me what you think.

Version 0.3.1 has added support for writing import libraries. Version
0.3.2 fixed creating archives containing members of import libraries.
Version 0.3.3 fixed building on big-endian systems.
Most float functions are marked `#[inline]` so any float symbols used by
these functions only need to be provided if the function itself is used.
RFL recently noticed that `next_up`, `next_down`, and `midpoint` for
`f32` and `f64` are not inline, which causes linker errors when building
with certain configurations [1].
Add the missing attributes so the symbols should no longer be required.

The object crate was recently updated to recognize the 32-bit SPARC
ELF targets EM_SPARC and EM_SPARC32PLUS, so the proper architecture
for 32-bit SPARC can now be set in rustc_codegen_ssa.
