Change Details

Linker might relax adrp + ldr got address loading to adrp + add for local non-preemtable symbols (e.g. hiddeng/protected/symbols in executable). As usually linker doesn't change relocations properly after releaxation, so we have to handle such cases by ourselves. To do that during relocations reading we change LD64 reloc to ADD if instruction missmatch found and introduce FixRelaxationPass that founds ADRP+ADD pairs and after perfoming some checks we're replacing ADRP target symbol to already fixed ADDs one.
