The labels for nodes in DOT can be expressed using HTML syntax
which allows colour to be specified within the text.  Add a
query to DefaultDOTGraphTraits defaulting to false that indicates
that the labels for nodes should be in HTML format.  This is
a prerequisite change for a new IR change reporter that will
presented in a tutorial in the LLVM developer's conference in Oct, 2020
(see https://hotcrp.llvm.org/usllvm2020/paper/29 for more details).
