Add support for ARIA 1.1 attribute 'aria-placeholder'.
Defines a short hint (a word or short phrase) intended to aid the user with data entry when the control has no value. A hint could be a sample value or a brief description of the expected format.

There's already a placeholderValue() function to get the value from placeholder attribute. Not sure the difference between placeholder and aria-placeholder from the spec. The logic for the patch is to get the value from aria-placeholder first, if not then check placeholder attribute.
