  [InferAddressSpaces] Fix constant replace to avoid modifying other functions (#70611)

A constant value is unique in llvm context. InferAddressSpaces was
replacing its users in other functions as well. This leads to unexpected
behavior in our downstream use case after the pass.

InferAddressSpaces is a function passe, so it shall not modify functions
other than currently processed one.
