Information about stack offset for arguments passed on the stack are complete after the PrologEpilogInserter pass. We're saving that information, and using them later in the phase of DWARF emitting.    
If they're available, interpret information about call-site-value, collected on IR level - through the DebugEntryValuesCallSite pass and location information for arguments.
