[Driver] Consolidate tools and toolchains by target platform. (NFC) Summary: (This is a move-only refactoring patch. There are no functionality changes.) This patch splits apart the Clang driver's tool and toolchain implementation files. Each target platform toolchain is moved to its own file, along with the closest-related tools. Each target platform toolchain has separate headers and implementation files, so the hierarchy of classes is unchanged. There are some remaining shared free functions, mostly from Tools.cpp. Several of these move to their own architecture-specific files, similar to r296056. Some of them are only used by a single target platform; since the tools and toolchains are now together, some helpers now live in a platform-specific file. The balance are helpers related to manipulating argument lists, so they are now in a new file pair, CommonArgs.h and .cpp. I've tried to cluster the code logically, which is fairly straightforward for most of the target platforms and shared architectures. I think I've made reasonable choices for these, as well as the various shared helpers; but of course, I'm happy to hear feedback in the review. There are some particular things I don't like about this patch, but haven't been able to find a better overall solution. The first is the proliferation of files: there are several files that are tiny because the toolchain is not very different from its base (usually the Gnu tools/toolchain). I think this is mostly a reflection of the true complexity, though, so it may not be "fixable" in any reasonable sense. The second thing I don't like are the includes like "../Something.h". I've avoided this largely by clustering into the current file structure. However, a few of these includes remain, and in those cases it doesn't make sense to me to sink an existing file any deeper.
