Pass name of object file to LLVM so it can correctly emit S_OBJNAME in pdb files on Windows
This should be the remaining fix to close https://github.com/rust-lang/rust/issues/96475
Setting ObjectFilenameForDebug in llvm::TargetOptions, so llvm it can emit S_OBJNAME in pdb files on Windows.
Without a proper pdb parsing I am not able to add a unit test for this. The string is already appearing in the pdb file so I cannot just use grep.

Don't ICE when no bound vars found while doing closure hir type check
The problem was that we were not visiting the const generic default argument in a bound where predicate when the HIR gets traversed in hir_analysis -> collect -> resolve_bound_vars.

GC the Stacked Borrows allocation history
This handles the biggest contributor to https://github.com/rust-lang/miri/issues/3080
The benchmark that this adds demonstrates the memory improvement here, but our benchmark setup doesn't record memory usage, and `hyperfine` doesn't support emitting memory usage stats. I ran this benchmark manually with `/usr/bin/time -v cargo +miri miri run` 🤷
bump ui test crate
The recommended way to run tests locally is `./miri bless -- -- --quiet`, which will show
* progress bars
* the currently running tests (allowing you to see which ones are still running towards the end of the test suite)
* the output of the currently running tests (if they are slow). This means slow running tests can output lines to `stderr` and the last line will be shown after the test name and updated every few hundred milliseconds.
As a side effect this PR also fixes#2998 and only builds dependencies if any tests actually need them (this means that with the next ui_test update we'll be able to merge all our test suites).
Also fixes https://github.com/rust-lang/miri/issues/3052.
Update crates for better MIPS R6 support
Update crates to remove dependency on old versions of rustix and linux-raw-sys. Update libc, rustix, and linux-raw-sys to enhance support for MIPS R6 introduced by #112374
Commands that do the update:
```shell
cargo +nightly update tempfile clap
cargo +nightly update linux-raw-sys rustix
```
Move `llvm.x86.*` shims into `shims::x86` and implement `_addcarry_u32` and `_subborrow_u{32,64}`
This PR moves all `llvm.x86.*` shims into `shims::x86` and adds `llvm.x86.addcarry.32`, `llvm.x86.subborrow.32` and `llvm.x86.subborrow.64`.
Additionally, it fixes the input carry semantics of `llvm.x86.addcarry.32`. The input carry is an 8-bit value that is interpreted as 1 when it is non-zero.

Add assembly test to make sure that inlining works as expected when closures inherit target features
Closes https://github.com/rust-lang/rust/issues/108338 (the added test proves that it is working correctly)
