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.

No functional changes intended. This updates the test case to use llvm-nm instead of the system nm. This fixes an instance over at the experimental build of rustc with HEAD LLVM: https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/8380#ef6f41b5-8595-49a6-be37-0eff80e0ccb5 It is related to rust-lang#94001. The issue is that this test uses the system nm, which may not be recent enough to understand the update to uwtable. This replaces the test to use the llvm-nm that should be recent enough (consistent with the LLVM sources we use to build rustc).
