These two tests utilize pre-generated opt-viewer output to diff against
a run of opt-viewer over a known yaml file.
cgi will not escape quotes by default, but html will.
Therefore, these tests were failing because they expected the old behavior
of "string", but was instead seeing "string".
This solution modifies the known test outputs to use the escaped quotes
rather than not escaping quotes during rendering for no particular reason.
It is notable that when testing the optimization records generated by
LLVM, there was never quotes in the remarks I could find, specifically in
the Callee field where they exist in the pre-generated yaml for testing.
