I have never used them myself, so I can talk about what they do, not
what they are used for. They produce exception handling tables that
look similar to (are?) the ones specified by the x86_64 abi. This
tables are used by stack unwinders and could probably be used to JIT
code that uses "zero cost" exceptions.
