…smute_obligation_for_reporting`

The `_umtx_time` flags check in `read_umtx_time` used equality (`flags == abs_time`) instead of bitwise AND (`flags & abs_time != 0`) to detect `UMTX_ABSTIME`. While functionally equivalent for current valid inputs (0 or `UMTX_ABSTIME` alone), the equality check would silently treat an absolute timeout as relative if `flags` had `UMTX_ABSTIME` set alongside other bits. Additionally, unknown flags were silently accepted, whereas the FreeBSD kernel (`umtx_copyin_umtx_time()` in `kern_umtx.c`) rejects them with `EINVAL`. The fix adds validation that rejects unsupported flags and switches to the standard bitwise AND pattern used elsewhere in the codebase (e.g. `O_APPEND`/`O_TRUNC` checks in `fs.rs`).

Windows: Implement MoveFileExW shim

Remove the `compiler-builtins` feature from default because it prevents testing via the default `cargo test` command. It made more sense as a default when `compiler-builtins` was a dependency that some crates added via crates.io, but is no longer needed. The `rustc-dep-of-std` feature is also removed since it doesn't do anything beyond what the `compiler-builtins` feature already does.

…-normalization-ice, r=lcnr Avoid ICE when param-env normalization leaves unresolved inference variables Fixes rust-lang#153354 Because the impl is already ill-formed, those variables are not fully constrained, so zfully_resolve` fails. We previously treated that as an immediate compiler bug with `span_bug!`, which caused an ICE on invalid input.

…donszelmann,bjorn3 Fix EII function aliases eliminated by LTO Add EII function aliases to `llvm.compiler.used` so that LLVM's LTO passes do not eliminate them. Fixes rust-lang#153645 Tracking issue: rust-lang#125418

@jdonszelmann

…r=jdonszelmann Fix regression when dealing with generics/values with unresolved inference Follow up for rust-lang#151703, fixing regression caused in rollup rust-lang#152825 Forgot to handle generics & unresolved inference variables (as in `get_safe_transmute_error_and_reason`) in my previous PR. This followup checks for them before trying to normalize. I am not completely sure its right approach to have this check cloned but as `select_transmute_obligation_for_reporting` fn just chooses obligation and doesn't actually return an error, this check shouldn't be removed from `get_safe_transmute_error_and_reasnon`. If there is any better solution, let me kmow. Fixes: rust-lang#153755 r? @jdonszelmann

…t-ne-suggestion-span, r=JohnTitor Skip suggestions pointing to macro def for assert_eq Fixes rust-lang#146204 It's better to suggest: ```console help: consider borrowing here --> src/main.rs:3:16 | 3| assert_ne!(&buf, b"----"); | + ``` but i don't want to give a too heuristic but not general enough fix, let suppress them.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
