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 a benchmark for document.getElementsByTagName().
This benchmark covers 'getElementsByTagName (not in document)',
'getElementsByTagName', 'getElementsByName (not in document)'
and 'getElementsByName' in Dromaeo/dom-query.html, and other DOM
methods that return a NodeList.

Test results in my Linux desktop:

RESULT Bindings: get-elements-by-tag-name= 364.542328875 runs/s
median= 366.972477064 runs/s, stdev= 5.25387955333 runs/s, min= 351.317440402 runs/s, max= 368.421052632 runs/s
