With the type matching it matches on exactly 'if src_type is
dst_type:' so you can't use 'and' and such... perhaps I should turn
these expression into a node with the constant value first and then
see if the result of the entire expression is known at compile time?
Yes, that's exactly what I was thinking you should do.
For now, you could simply (try to) re-run the ConstantFolding transform
after the type splitting. It will evaluate constant expressions and also
drop unreachable branches from conditionals.
