Optimize CSS attribute selector matching:

Browse Source 
Resolve standard property definitions and data-attribute classification
  when selectors are parsed, avoiding repeated specification lookups and
  attribute-name checks during matching.

  Fast-path existence-only data selectors without retrieving their values,
  while preserving all attribute operator behavior. Add standard-property
  coverage and an attribute-focused benchmark showing a 41.7% reduction
  in matching time.
