Implement a few symbolic constant folding things. X ? Y : Y is Y.
...
Fold:
seteq ({ short }* cast (int 1 to { short }*), { short }* null)
setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*))
to false/true. These last two commonly occur in the output of compilers that
tag integers, like cozmic's scheme compiler.
