ext/ripper/tools/dsl.rb: Use String#sub instead of delete_suffix

2018-01-20T17:52:51+00:00

It fails when baseruby is old.

ext/ripper/tools/dsl.rb: Serialize dispatch calls

2018-01-20T17:45:24+00:00

To avoid the unspecified behavior (the evaluation order of arguments).
In `$$ = foo(bar(), baz());`, it is unspecified which `bar` or `baz` is
called earlier.

This commit changes the code to `v1=bar(); v2=baz(); $$ = foo();`.

parse.y: Remove unneeded var_field_1 trick

2018-01-20T06:11:21+00:00

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`.
