Sink DI metadata usage out of MachineInstr.h and MachineInstrBuilder.h
MachineInstr.h and MachineInstrBuilder.h are very popular headers,
widely included across all LLVM backends. It turns out that there only a
handful of TUs that actually care about DI operands on MachineInstrs.
After this change, touching DebugInfoMetadata.h and rebuilding llc only
needs 112 actions instead of 542.
