With optimzations disabled compilers have trouble doing dead code elimination on 'if (foo && 0)' expressions, while 'if (0 && foo)' still works, so use the latter to avoid problems. Bug-Id: 707

This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
