In https://reviews.llvm.org/D122373 I delayed the search for the SDK filepath until the simulator platform is Created. In the qProcessInfo binary-addresses key, I have to force-Create every platform to find one that can handle a kernel fileset; this forced all of the simulator platforms to create, taking the SDK filepath discovery perf hit. This patch delays that path search further until the Apple Simulator platform calls a method that actually needs the full filepath; it saves the SDK name ("WatchSimulator.sdk" etc) until it needs to expand it.
