Fixes https://github.com/llvm/llvm-project/issues/55804 The lexing order is already bookkept in DelayedCXXInitPosition but we were not using it based on the wrong assumption that inline variable is unordered. This patch fixes it by ordering entries in llvm.global_ctors by orders in DelayedCXXInitPosition. for llvm.global_ctors entries without a lexing order, ordering them by the insertion order. (This *mostly* orders the template instantiation in https://reviews.llvm.org/D126341 intuitively, minus one tweak for which I'll submit a separate patch.)
