SIL optimizations may rewrite profiling intrinsics in a way that IRGen can't lower (r://39146527). Don't claim that a coverage mapping has a guaranteed associated symbol table entry when this happens. I have not added a test, as this is a defensive workaround until we can land add a SIL verifier check that prevents profiling intrinsics from being rewritten. rdar://40133800
