This continues the effort to reduce header footprint and improve build speed by removing clang and other unnecessary headers from Target.h. In one case, some headers were included solely for the purpose of declaring a nested class in Target, which was not needed by anybody outside the class. In this case the definition and implementation of the nested class were isolated in the .cpp file so the header could be removed. llvm-svn: 231107
