llvm: migrate to new parameter-bearing uwtable attr
In https://reviews.llvm.org/D114543 the uwtable attribute gained a flag so that we can ask for sync uwtables instead of async, as the former are much cheaper. The default is async, so that's what I've done here, but I left a TODO that we might be able to do better. While in here I went ahead and dropped support for removing uwtable attributes in rustc: we never did it, so I didn't write the extra C++ bridge code to make it work. Maybe I should have done the same thing with the `sync|async` parameter but we'll see.
