* Change `Symbol::flags` to a `std::atomic<uint16_t>` * Add `llvm::parallel::threadIndex` as a thread-local non-negative integer * Add `relocsVec` to part.relaDyn and part.relrDyn so that relative relocations can be added without a mutex * Arbitrarily change -z nocombreloc to move relative relocations to the end. Disable parallelism for deterministic output. MIPS and PPC64 use global states for relocation scanning. Keep serial scanning. Speed-up with mimalloc and --threads=8 on an Intel Skylake machine: * clang (Release): 1.27x as fast * clang (Debug): 1.06x as fast * chrome (default): 1.05x as fast * scylladb (default): 1.04x as fast Speed-up with glibc malloc and --threads=16 on a ThunderX2 (AArch64): * clang (Release): 1.31x as fast * scylladb (default): 1.06x as fast Reviewed By: andrewng Differential Revision: https://reviews.llvm.org/D133003
