[PATCH] D31900: [AddDiscriminators] Assign discriminators to memset/memcpy/memmove intrinsic calls.

I don't quite understand why you want to set a new discriminator for memcpy builtin. What optimization would it enable? For normal function calls, we need to have discriminator to distinguish callsites in the same BB so that we can annotate the inlined callee correctly. But for the memcpy case, looks like adding a new discriminator does not help down-stream optimizations like inlining?
