[WebAssembly] Add reference types target feature
ClosedPublic

Details

Summary

This adds the reference types target feature. This does not enable any
more functionality in LLVM/clang for now, but this is necessary to embed
the info in the target features section, which is used by Binaryen and
Emscripten. It turned out that after D69832 -fwasm-exceptions crashed
because we didn't have the reference types target feature.

Couldn't we also check the that attribute is attached to the dummy function?

It's a good idea if we also check if the target feature also appears in the target features section. But because either setting the attribute in a function or giving the command line attribute argument equally sets the feature in the target features section, I'll test the arg in this file, and test the function attribute in the existing target-features.ll.
