This removes unused includes (and forward declarations) as suggested by include-what-you-use. If a transitive include of a removed include is required to compile a file, I added the required header (or forward declaration if suggested by include-what-you-use). This should reduce compilation time and reduce the number of iterative recompilations when a header was changed. llvm-svn: 357209
