  llvm-reduce: Don't replace intrinsic calls with undef

These don't really have function bodies to try to eliminate. This also
has a good chance of just producing invalid IR since intrinsics can
have special operand constraints (e.g. metadata arguments aren't valid
for an arbitrary call). This was wasting quite a bit of time producing
and failing on invalid IR when replacing dbg.values with undefs.
