Integer range inference has been swapped to the new framework. The integer value range lattices automatically updates the corresponding constant value on update.

Just short-circuit when a change was made, the erased value is invalid
after that. Found by asan.
This pass looks like it could use rewrite patterns instead which don't
have this issue, but let's fix the asan build first.
If all the arguments to and results of an operation are known to be
non-negative when interpreted as signed (which also implies that all
computations producing those values did not experience signed
overflow), we can replace that operation with an equivalent one that
operates on unsigned values.
Such a replacement, when it is possible, can provide useful hints to
backends, such as by allowing LLVM to replace remainder with bitwise
operations in more cases.
