Not deleting the loose instruction with metadata associated to it causes an assertion when the LLVMContext is destroyed. This was previously hidden by the fact that llvm-c-test does not call LLVMShutdown. The planned removal of ManagedStatic exposed this issue. Differential Revision: https://reviews.llvm.org/D129114
