We can use goblin to parse IR nodes, but parsing IR edges might be a little trickier. The DW_TAG_call_site ⁰ ¹ attribute, if present in the DWARF debugging information, could help. Otherwise, we'll need to disassemble instructions.

I've got some code in ddbug that uses capstone to disassemble instructions to find calls, and a copy in findpanics too. It's currently incomplete, but I'm working on updating it. Maybe I should put this in its own crate so that twiggy can use it too?

@philipc that would be greatly appreciated! Thank you for offering :slightly_smiling_face:
