(Fixed an issue about GOT on a copy relocated alias.) (Fixed an issue about not creating r_addend=0 IRELATIVE for unreferenced non-preemptible ifunc.) The idea is to make scanRelocations mark some actions are needed (GOT/PLT/etc) and postpone the real work to postScanRelocations. It gives some flexibility: * Make it feasible to support .plt.got (PR32938): we need to know whether GLOB_DAT and JUMP_SLOT are both needed. * Make non-preemptible IFUNC handling slightly cleaner: avoid setting/clearing sym.gotInIgot * -z nocopyrel: report all copy relocation places for one symbol * Make GOT deduplication feasible * Make parallel relocation scanning feasible (if we can avoid all stateful operations and make Symbol attributes atomic), but parallelism may not be the appealing choice Since this patch moves a large chunk of code out of ELFT templates. My x86-64 executable is actually a few hundred bytes smaller. For ppc32-ifunc-nonpreemptible-pic.s: I remove absolute relocation references to non-preemptible ifunc because absolute relocation references are incorrect in -fpie mode.
