I am seeing the following assertion in leak detector. /llvm/lib/VMCore/LeakDetector.cpp:43: void<unnamed>::LeakDetectorImpl<T>::addGarbage(const T*) [with T = void]: Assertion `Ts.count(Cache) == 0 && "Object already in set!"' failed. I am creating a list of instructions using BuildMI() and adding them to a basic block using BB->insert(). I am seeing this assertion after some number of insertions. Am I doing...

The `Metadata`/`Value` split (PR21532) landed in r223802 -- at least, the C++ side of it. This was a rocky day, but I suppose that's what I get for failing to stage the change in smaller pieces. As of r223916 (lldb), I'm not aware of any remaining (in-tree) breakage, so if I've missed some problem in the sea of buildbot errors, please flag me down. I'll follow up soon with
