r192612 - Lit tests for Microsoft C++ record layout.

[Warren Hunt]

They're just markers.  I have a little test harness that prints all of the
bytes of a record and these make it very easy to read.  They're not
relevant to being tested in lit and can be removed.  They're vestiges when
turning my layout tests into lit tests and I was lazy and didn't remove
them.  I may someday.
