Yes indirect jumps are 'interesting', is there anything in the debug
info that will help us out with the possible target sites?

Also what generates indirect jumps, switch() stmts? Indirect function
call that get optimized might also be, but hopefully DWARF would tell us
about that and allow us to know the state right after the jump.
