The purity analysis process is very dependent on the node tree being
as clean as possible, and so depends on a fair few merge requests that

strips unnecessary typeconv nodes (this helps a lot with constant

I didn't say that you shouldn't clean up the tree for your purity
analysis (that sounds so wrong :P ), I simply asked what you meant with
“share the same field” and if it is what I think it is then it's a bad
idea and you shouldn't “share the same field” but introduce your own.
