Rollup merge of rust-lang#78988 - alexcrichton:one-more-intrinsic, r=sfackler

Dylan-DPC · web-flow · commit d57212d49e8c · 2020-11-15T03:02:57.000+01:00
Fix an intrinsic invocation on threaded wasm This looks like it was forgotten to get updated in rust-lang#74482 and wasm with threads isn't built on CI so we didn't catch this by accident.
