Created an attachment (id=133905)
 --> (https://bugs.webkit.org/attachment.cgi?id=133905&action=review)
1) Address review comments, 2) Do work to determine cell role only once, 3) Separate/clarify tests and provided -expected files for Chromium-win port

I'm having a bit of trouble using uploat-webkit-patch and prepare-changeLog from Windows, so for now here are the comments inline.

Ensure that the table header roles (row/column) are exposed correctly. Neither IAccessible2 nor ATK/AT-SPI use something like AXColumnHeaderUIElements/AXRowHeaderUIElements ... Windows/Linux ATs expect the role to provide this information.

At first I tried to use the results of AccessibilityTable[Row|Column]->headerObject() but given that the role needed to be const I ran into dependency issues getting the information at cell construction time. For bug 81681 (multiple row/column headers per cell) it might make sense to reuse the information from the role calculation for AXColumnHeaderUIElements and AXRowHeaderUIElements.
