As suggested by John. This results in the symbols being coalesced at static link time into a single strong symbol in a built dylib. Fortunately we don't care about the contents of these global symbols, so common linkage's forced zero-initialization is fine. (Hey, C's tentative definitions are useful for something after all.) rdar://problem/20072051 Swift SVN r25804
