This patch changes the return value of Platform::GetName() to a StringRef, and uses the opportunity (compile errors) to change some callsites to use GetPluginName() instead. The two methods still remain hardwired to return the same thing, but this will change once the ideas in <https://discourse.llvm.org/t/multiple-platforms-with-the-same-name/59594> are implemented.
