General support for unwind info code generation was added back then, and
was mostly complete around LLVM 8.
But support for generating unwind info in assembly (both inline and
external) wasn't added back then; that was added recently in the master
branch though. See e.g.
for examples on the syntax. As the instruction set and unwind opcodes
differ between x86_64 and arm64, the assembly directives also differ
