Put ELF COMDAT relocations into the relevant COMDAT group. Patch from Игорь Пашев (I do hope we support utf-8 commit messages; I also hope he'll forgive me for transliterating it as Igor Pashev in case things go horribly wrong). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186034 91177308-0d34-0410-b5e6-96231b3b80d8

Write sections mostly in one pass. During ELF writing, there is no need to further relax the sections, so we should not be creating fragments. This patch avoids doing so in all cases but debug section compression (that is next). Also, the ELF format is fairly simple to write. We can do a single pass over the sections to write them out and compute the section header table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236235 91177308-0d34-0410-b5e6-96231b3b80d8

Write the section header string table directly to the output stream. Instead of accumulating the content in a fragment first, just write it to the output stream. Also put it first in the section table, so that we never have to worry about its index being >= SHN_LORESERVE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236145 91177308-0d34-0410-b5e6-96231b3b80d8
