[PECOFF] Emit BSS section. llvm-svn: 187460

[PECOFF] Add a generic section writer. Instead of having multiple SectionChunks for each section (.text, .data, .rdata and .bss), we could have one chunk writer that can emit any sections. This patch does that -- removing all section-sepcific chunk writers and replace them with one "generic" writer. This change should simplify the code because it eliminates similar-but- slightly-different classes. It also fixes an issue in the previous design. Before this patch, we could emit only limited set of sections (i.e. .text, .data, .rdata and .bss). With this patch, we can emit any sections. llvm-svn: 195797

[PECOFF] Writer: Remove NULL padding at the end of each section. If section size is not multiple of 512, the writer added NULL bytes at the end of it to make it so. That is not required by the PE/COFF spec, and the MSVC's linker does not do that too. So we don't need to do that, too. llvm-svn: 197002
