parse.y: Remove unneeded var_field_1 trick
I thought this trick was needed because the result of var_field was passed to different arguments, as follows: ``` $1 = var_field(p, $1); $$ = backref_assign_error(p, $1, $1, &@$); ``` Currently the DSL supports that one result is passed to one argument. However, after the refactoring, I found that `backref_assign_error` uses only one `$1`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61979 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
