GCC seems to limit it to 32 bits as well, I guess there aren't many
cases with line tables bigger than 4G... ;)

I had problems with relocation in the past (typeinfo, exceptions) in
clang on ARM, and sent a patch to add some of it to the AsmPrinter,
but that was a dirty work-around the issue.

What is the official mechanism in MC to treat relocations? Where
should I add target-specific relocation types and how to write them in
ASM or ELF?
