We have at least test in WebAssembly (tls-local-exec.ll) using sed. There are many in RISCV which uses sed to replace types depending on current running arch, etc. We need this here to ensure that without reference types we don't add a table and if we do have reference types, the result is correct. Alternatively we need another test file. I am happy to do that if you're not keen on sed but sed is very much used together with lit tests in general.
