For now, this removes all `llvm.dbg.*` calls from LLVM IR. This is
useful to keep coloring the line correspondence between source and IR,
while not polluting the IR with the debug intrinsics.
Admittedly, I don't have much of a clue of what's going on here, so I
might be missing obvious adaptions (e.g. can we disable this for all
non-LLVM compilers for now somehow?).
Also, not really a Node.JS testing wizard either... 🤷🏼
Just wanted this really bad for a workshop that's coming up soon ^^
Only tested with my system's default `clang` for now.
Fixes#5044
