Implement createLabel() to allocate DILabel objects.
Implement insertLabel() to insert llvm.dbg.label intrinsic function in LLVM IR.

Clang could use DIBuilder::createLabel() to allocate DILabel, then pass the object
to DIBuilder::insertLabel() to insert llvm.dbg.label intrinsic function in LLVM IR.
