ParserOutput::getTOCHTML() is being deprecated, and all skins are now
generating the TOC from the TOCData returned by
ParserOutput::getTOCData(). The SHOW_TOC flag was introduced in core
to determine if the TOC should be shown, but Vector-2022 *may* begin to
use other heuristics to determine whether to show the TOC (T315862).
We're conservatively going to process the TOC as long as there is
TOC present to process.

We verify that they appear in the action=parse API output.
We should also have a test to verify that they appear in the Vector
2022 skin, but that might have to be done as a browser test.
