Eliminate a 'tst' that immediately follows an 'and'
...
by morphing the 'and' to its recording form 'andS'.
This is basically a test commit into this area, to
see whether the bots like me. Several generalizations
can be applied and various avenues of code simplification
are open. I'll introduce those as I go.
I am aware of stylistic input from Bill Wendling, about
where put the analysis complexity, but I am positive
that we can move things around easily and will find a
satisfactory solution.

When a function-local value with function-local metadata uses gets RAUWed with a
...
non-function-local value, it may result in the metadata no longer needing to be
function-local. Check for this condition, and clear the isFunctionLocal flag, if
it's still in the uniquing map, since any node in the uniquing map needs to have
an accurate function-local flag.
Also, add an assert to help catch problematic cases.
