Enable rustdoc to document safe wasm intrinsics This commit fixes an issue not found during #84988 where rustdoc is used to document cross-platform intrinsics but it was requiring that functions which use `#[target_feature]` are `unsafe` erroneously, even if they're WebAssembly specific. Rustdoc today, for example, already has a special case where it enables annotations like `#[target_feature(enable = "simd128")]` on platforms other than WebAssembly. The purpose of this commit is to relax the "require all `#[target_feature]` functions are `unsafe`" requirement for all targets whenever rustdoc is running, enabling all targets to fully document other targets, such as WebAssembly, where intrinsics functions aren't always `unsafe`. 2021-06-04 01:56:31 +00:00			`//@ check-pass`
