@aprantl Thanks again for your comments!

The patch is needed to describe a call site to an external function. Currently, we do not have all necessary info for the debug call site (particular debug subprogram is missing for the external function). Since we can describe call site parameters for calls like that, we are producing additional subprogram for the declaration of the extern function by marking it with the `DISPFlagDeclForCallSite` flag.
Basically, this is improvement of existing call site debug info production.
