[PATCH] D87202: Add new choices dot-cfg and dot-cfg-quiet to print-changed which creates a website of DOT files showing colourized changes as the IR is changed by passes in the new pass manager pipeline.

http://graphviz.org/docs/outputs/pdf/ mentions that whether PDF output is supported by dot depends on how Graphviz was configured; we cannot assume that if dot is present, it will support PDF. Is there some way to ensure that in this case, the test is skipped?
