replace "// @" with "//@ ", and fix the tests so they actually pass, after directives are checked

Removes an ABI hack that used `<2 x i64>` to return `i128` in `xmm0` on Windows [1]. [1]: rust-lang/compiler-builtins#759 Link: rust-lang#116558 Link: rust-lang/compiler-builtins#758

…ng, r=Noratrieb Misc. `rustc_codegen_ssa` cleanups 🧹 Just a bunch of stuff I found while reading the crate's code. Each commit can stand on its own. Maybe r? `@Noratrieb` because I saw you did some similar cleanups on these files a while ago? (feel free to re-assign, I'm just guessing)

intrinsics: unify rint, roundeven, nearbyint in a single round_ties_even intrinsic LLVM has three intrinsics here that all do the same thing (when used in the default FP environment). There's no reason Rust needs to copy that historically-grown mess -- let's just have one intrinsic and leave it up to the LLVM backend to decide how to lower that. Suggested by `@hanna-kruppe` in rust-lang#136459; Cc `@tgross35` try-job: test-various

Add binary_format to rustc target specs Added binary format field to `TargetOptions` Fixes rust-lang#135724 r? `@Noratrieb`

…est-directives, r=fmease Fix rustdoc test directives that were accidentally ignored 🧐 Replace "// `@"` with "//@ ", and fix the tests so they actually pass, after directives are checked. ~~Only the first commit is mandatory, other two are small drive-bys.~~

Update `compiler-builtins` to 0.1.147 Removes an ABI hack that used `<2 x i64>` to return `i128` in `xmm0` on Windows [1]. [1]: rust-lang/compiler-builtins#759 Link: rust-lang#116558 Link: rust-lang/compiler-builtins#758 try-job: x86_64-mingw-1 try-job: x86_64-mingw-2

FIx `sym` -> `syn` typo in tail-expr-drop-order type opt-out The rust-lang#131326 PR attempts to reduce some false positives for the `tail_expr_drop_order` lint by hard-coding some common ecosystem crate names. Specifically, I believe it attempts to opt out the drop impls from `syn` which only exist as optimizations. However, this was typo'd like "sym", which is a crate that has been [yanked](https://crates.io/crates/sym) (lol). This PR fixes that. cc `@dingxiangfei2009` `@nikomatsakis` -- did I mistake this? Was this meant to be a different crate? `@bors` rollup

Can we r- this for now? Otherwise we will have a broken nightly tomorrow... We need #137476 to avoid broken nightly.
