…pport Add `stat` and `lstat` shims for all Unixes
…x2var_epi64 Implement `_mm512_permutex2var_epi64` shim
Make FileMetadata track Unix-specific fields as optional data. Advertise STATX_* bits only for metadata that is actually available. Add libc-fs coverage for statx on file paths, file descriptors, and AT_EMPTY_PATH on pipes
shims: improve Linux statx
…tcp-proto Allow setting `IPPROTO_TCP` as protocol in `socket` syscall
This PR tries to address rust-lang/unsafe-code-guidelines#584 (comment). It is part of a bachelor thesis supervised by @JoJoDeveloping and @RalfJung, for more information, see: https://github.com/user-attachments/files/26537277/Project_Description.pdf. This implements the checking for implicit writes for Tree Borrows. It is disabled by default but can be enabled using the `-Zmiri-tree-borrows-implicit-writes` flag. When it is enabled, Miri inserts a write for all mutable borrows on function entry. This enables the optimization implemented here: rust-lang#155207

miri subtree update We want to get `-Zmiri-tree-borrows-implicit-writes` into a nightly ASAP, hence the out-of-schedule sync. Subtree update of `miri` to rust-lang/miri@6961dab. Created using https://github.com/rust-lang/josh-sync. r? @ghost
