This PR fixes the handling of the `never_extract` attribute in the compiler's CSE pass. There is an interesting debate to be had about exactly how hard the compiler should try to avoid duplicating anything that transitively uses `never_extract`, but this is the simplest form and roughly matches the check in the old compiler (although due to different handling of local function decls in the two compilers, the consequences might be slightly different). This gets half of the way to #8944. |
