When emitting nested block definitions, the insert-at-point variant of DIBuilder::insertDeclare() could be called with the insertion point set to the end-of-BasicBlock sentinel, causing the parent pointer of the CallInst to be set to the intentionally bogus value of the sentinel. Fixed by conditionally invoking the correct version of insertDeclare(). rdar://problem/19034882 llvm-svn: 222487
