This patch added /dwodir to lld/COFF which is equivalent to lld/ELF option -plugin-opt=dwo_dir=. This option tells LTO backend to create dwo directory and files and all dwo files will be in it. Otherwise all dwarf sections will be embeded into image even if -gsplit-dwarf is specified when using LTO. Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D154070
