In this pull request, I suggest to use "this symbol" to only refer "this production", and to use "symbol" to refer sub-components of Parse Node.
In many abstract algorithms which use same nonterminal symbols for both whole productions and sub-components in standard specification (Evaluation of Tagged Templates, Property Accessors, etc), they use "this MemberExpression"(or other symbol) to refer production itself. Thus, I revised all of them which makes confusions compared to existing specifications.
