Fix dump-ice-to-disk for RUSTC_ICE=0 users
Before this change, the test fails if you run it with `RUSTC_ICE=0`.

run-make: explaing why fmt-write-bloat is ignore-windows
The trouble here is that libc doesn't exist on Windows. Well it kinda does but it isn't called that so we substitute a name that works. Ideally finding necessary libs for the platform would be done at a higher level but until then this should work.

run-make: enable msvc for staticlib-dylib-linkage
`-Zstaticlib-allow-rdylib-deps` on MSVC returns things like `/LIBPATH:R:\rust\build\x86_64-pc-windows-msvc\test\run-make\staticlib-dylib-linkage\rmake_out`. That is a linker argument rather than a `cc` argument. Which makes sense because rustc interacts directly with the linker on MSVC targets. So we need to tell the C compiler to pass on the arguments to the linker.

run-make: enable msvc for redundant-libs
The issue here was that `foo` was not exporting any functions therefore creating an import library was unnecessary and elided by the linker.
I fixed it by exporting the functions.

Migrate `staticlib-dylib-linkage` `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).
I'm quite sure this has the same issue as the one brought up in [this discussion](https://github.com/rust-lang/rust/pull/128407#discussion_r1702439172), so I elected to keep the ignore MSVC.

Add tests to ensure MTE tags are preserved across FFI boundaries
Added run-make tests to verify that, between a Rust-C FFI boundary in both directions, any MTE tags included in a pointer are preserved for the following pointer types, as well as any information stored using TBI:
- int
- float
- string
- function

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.

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.

run-make: Enable msvc for `no-duplicate-libs` and `zero-extend-abi-param-passing`
The common thing between these two tests is to use `#[link(..., kind="static")]` so that it doesn't try to do a DLL import.
`zero-extend-abi-param-passing` also needs to have an optimized static library but there's only helper function for a non-optimized version. Rather than copy/pasting the code (and adding the optimization flag) I reused the same code so that it more easily be kept in sync.

Enable msvc for link-args-order
I could not see any reason in #70665 why this test needs to specifically use `ld`. Maybe to provide a consistent linker input line? In any case, the test does work for the MSVC linker.

run-make: enable msvc for `link-dedup`
This is just a case of differing style of linker arguments.
I also cleaned up a bit where we were running the same command three times in a row. Instead I reused the output.
One thing that confused me is why we were testing for the same lib three times in a row but not two. After figuring that out I added a note to hopefully save future readers some confusion.

add test for symbol visibility of `#[naked]` functions
tracking issue: #90957
This test is extracted from https://github.com/rust-lang/rust/pull/128004
That PR attempts to generated naked functions as an extern function declaration, combined with a global asm block that provides the implementation for that declaration.
In order to link declaration and definition together, some flavor of external linking must be used: LLVM will error for other linkage types. Specifically the allowed options are `#[linkage = "external"]` and `#[linkage = "extern_weak"]`. That is kind of an implementation detail though: to the user, a naked function should just behave like a normal function.
Hence it should be visible to the linker under the same circumstances as a normal, vanilla function and have the same attributes (Weak, External). Getting this behavior right will require some care, so I think it's a good idea to lock it in now, before making any changes, to make sure we don't regress.
Are there any interesting cases that I missed here? E.g. is checking on different architectures worth it? I don't think the other binary types (rlib etc) are relevant here, but may be missing something.

Don't ICE when getting an input file name's stem fails
Fixes #128681
The file stem is only used as a user-friendly prefix on intermediary files. While nice to have, it's not the end of the world if it fails so there's no real reason to emit an error here. We can continue with a fixed name as we do when an anonymous string is used.
