Hmm. I had suggested a bit on FunctionDecl on the assumption that this would often be controlled globally, maybe by using a flag to control the default or by activating a #pragma before including all the headers. Actually, I could even imagine a target (maybe a GPU target?) even opting-in to this behavior by default. If we're going to use an Attr, we need to make sure it doesn't get added unless the current #pragma state is different from the global default; we really don't want to be allocating an attribute for every function definition in the translation unit.
