* libSyntax: Parse member access expression. This patch uses createNodeInPlace from syntax parsing context API to merge an expression with its suffix to create recursive nodes such as member access expression. Meanwhile, this patch breaks down a signed integer or float literal to a prefix operator expression. This expression consists of two parts: an operator and the following expression. This makes literals like "+1" or "-1" no different from other prefix unary expressions such as "!true".
