Do other tests need to be updated (aarch64-got-relocations.s and maybe smth else)? They do not include disassembler test so they won't check that the ldr instruction immediate is filled correctly, but maybe we want to check that other stuff works with `GOT_LD_PREL19` the same way as with `ADR_GOT_PAGE` + `LD64_GOT_LO12_NC`
