This patch extends IRBuilder to allow adding/preserving arbitrary metadata on created instructions. Instead of using references to specific metadata nodes (like DebugLoc), IRbuilder now keeps a vector of (metadata kind, MDNode *) pairs, which are added to each created instruction. The patch itself is a NFC and only moves the existing debug location handling over to the new system. In a follow-up patch it will be used to preserve !annotation metadata besides !dbg. The current approach requires iterating over MetadataToCopy to avoid adding duplicates, but given that the number of metadata kinds to copy/preserve is going to be very small initially (0, 1 (for !dbg) or 2 (!dbg and !annotation)) that should not matter.
