Reviewed by Ryosuke Niwa.

We should remove Bindings/dom-attributes.html and instead add more
reasonable micro benchmarks by classifying DOM binding call paths.
This patch adds seven micro benchmarks for DOM bindings.

id-getter.html covers 'element.property' in Dromaeo/dom-attr.html,
'innerHTML' in Dromaeo/dom-modify.html, and other DOM attributes that
return a String.

id-setter.html covers 'element.property = value' in Dromaeo/dom-attr.html,
and other DOM attributes that sets a String.

undefined-id-getter.html covers undefined DOM attributes that return an empty String.

append-child.html covers 'appendChild' and 'removeChild' in Dromaeo/dom-modify.html.

insert-before.html covers 'insertBefore' in Dromaeo/dom-modify.html and replaceChild().

create-element.html covers 'createElement', 'createTextNode' and 'cloneNode'
in Dromaeo/dom-modify.html, and other DOM methods that return a new Node object.

node-list-access.html covers 'childNodes' in Dromaeo/dom-traverse.html,
and other DOM attributes that access NodeList.
