In this function a string is converted to UTF8, if there are
non-printing characters in the original string, the generated string
will be shorter. Thus using the original string length for iteration
range will cause an OOB read.

It is hard to tell if there is some unsavory stuff going on with

Because the invisible temporary goes out of scope at the next

Also avoid returning const string references since the cost is

- Changes the URL to retrieve baselines which returns the
baselines based on the issue number (if available)
- Compare against a single baseline (instead of multiple)
- Writes the results of comparing to the baselines to a
separate output file that can then be parsed by the
recipe code.

Many of these are converting ByteString => c_str => ByteStringView, since
the ByteStringView ctor is implicit. This is unfortunate, since that
involves a strlen() which the ByteString already knows if we use
AsStringView() instead.
This changed one test result where we can now return the string
"\0" instead of "" -- since strlen no longer eats the NUL. This
seems consistent, say, with String.fromCharCode().

We speculate that the bug that makes the comparison operator irreflexive
might be the cause of the segv on windows production code, should a
NaN sneak into the GraphicsData struct. In any event, should this
happen, the tree won't be correct with some nodes erroneously replaced.
Add a test which fails prior to the patch, but alas does not elicit
the segv.
Also move operator<() methods to .cpp file corresponding to .h file
in which they are delcared.

When calling the FXSYS_wctof method we currently pass in -1 from
AdvanceForNumber. This tells the method to calculate the string length.
This can be slow for a formcalc string with a lot of numbers.
This CL changes the call to pass in the length of remaining data in the
original string. This takes the MSAN runtime of the case in the linked
bug from ~21seconds to ~500ms. The debug runtime goes from ~2s to
~500ms.

The current code could cause FT to try to free memory allocated by the
