This is a test to ensure that both lldb is reconstructing the right
calling convention for a CXXRecordDecl as represented by:

   DW_CC_pass_by_reference
   DW_CC_pass_by_value

and to also make sure that the ASTImporter is copying over this
setting when importing the CXXRecordDecl via setArgPassingRestrictions.
