viml/parser/expressions: Finish parser

Note: formatc.lua was unable to swallow some newer additions to ExprASTNodeType 
(specifically `kExprNodeOr = '|'` and probably something else), so all `= …` 
were dropped: in any case they only were there in order to not bother updating 
viml_pexpr_debug_print_ast_node and since it is now known all nodes which will 
be present it is not much of an issue.
