verilog: fix multiple AST_PREFIX scope resolution issues - Root AST_PREFIX nodes are now subject to genblk expansion to allow them to refer to a locally-visible generate block - Part selects on AST_PREFIX member leafs can now refer to generate block items (previously would not resolve and raise an error) - Add source location information to AST_PREFIX nodes
