…e1-dead Start using comptime for reflection intrinsics and their wrapper functions r? @fee1-dead follow-up to rust-lang#148820 I needed to add some more rustc code because turns out I forgot to add tests to the previous PR which actually codegen while using comptime fns. Check builds never try to create optimized MIR, so no code ever hit the assert that prevents creating optimized MIR for comptime fns.

…7,Cyanoxygen platform support: add SNaN erratum to MIPS targets See issue rust-lang#68925. For now we can't do much better than just documenting this.

Add `or_try_*` variants for `HashMap` and `BTreeMap` Entry APIs This PR builds on [peterjoel's introduction of `or_try_*` variants for `HashMap`](rust-lang#120708) from the following [ACP](rust-lang/libs-team#336) Peter made. The tracking issue for this PR is [here](rust-lang#157354).

@petrochenkov

…t, r=petrochenkov Move symbol hiding code to a new file Move the symbol visibility editing code (`apply_hide` and helpers) from `archive.rs` into a new `symbol_edit.rs` module. This is a pure code move with no functional changes — extracted to reduce the size of `archive.rs` and to provide a natural home for future symbol editing logic (e.g. renaming, rust-lang#156950). Requested in rust-lang#156950 (comment). r? @petrochenkov
