We need to record debug information in LLVM IR. In LLVM
IR, LLVM uses metadata and intrinsic function to keep debug
information. So, we need to define new kind of metadata, DILabel, and
new intrinsic function, llvm.dbg.label, to associate DILabel with
label statement.

DILabel will contain name of the label, file metadata, line number,
and scope metadata.

Use class DILabel to store information of DILabel metadata.
