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

@ In C++, the instantiation of the template will come with linkonce (or
