Because of this reason, FPC only uses llvm.dbg.addr. But clang still

Done.
Just out of curiosity: Clang is by fpc used as a driver program, as it
is asier to call it than tools like llc, opt and llvm-linker ?
It's indeed easier, and it also supports some preprocessing that llc
doesn't (I don't remember what exactly llc didn't support, perhaps
comments). It's also faster since you call one tool rather than 2 or 3.
