Miri fixed a critical intrinsic handling bug on LoongArch that was causing panics, while the compiler absorbed routine subtree syncs and powerpc64 gained a second ABI target.

The most significant change hit the interpreter: Miri was forwarding full-width values to CRC intrinsic shims when LoongArch hardware only consumes the low 8/16/32 bits, causing panics on sign-extended inputs [1]. The fix masks off unused high bits before calling compute_crc32, making the shim match actual hardware behavior. Meanwhile, rustc merged a region inference refactor that simplifies initialization logic in the type checker [2], routine subtree pulls for Miri [3] and Clippy [4] landed cleanly, and the compiler now supports powerpc64-unknown-linux-gnuelfv2, a new target using the ELFv2 ABI instead of the legacy ELFv1 [5]. Over in rust-analyzer, the inline variable assist now works correctly inside macros [6], the extract_module handler completed its migration to the new SyntaxEditor abstraction [7], and the test suite shed unnecessary feature flags now that bindings_after_at, if_let_guard, and trait_upcasting are stable [8].
