For llvm-objdump, I changed it to display the target address instead of
`. + offset` in https://reviews.llvm.org/D76907 and several follow-ups
(b, bl, beq (Bcc) need separate changes)
(I changed x86 and aarch64 as well.)

I guess the `. + offset` form may be more suitable when comparing two -d output.
Do you have a suggestion for the option enabling the `. + offset` output
or do you other ideas making the output easier for -d comparison?
