This performs very conservative dependency generation for each compile task within a full compilation. Any source file, swiftmodule, or Objective-C header file that is /touched/ gets added to the dependencies list, which is written out on a per-input basis at the end of compilation. This does /not/ handle dependencies for the aggregated swiftmodule, swiftdoc, generated header, or linked binary. This is just the minimum needed to get Xcode to recognize what needs to be rebuilt when a header or Swift source file changes. We can revisit this later. This finishes <rdar://problem/14899639> for now. Swift SVN r18045
