The previous code always compared integers as 64-bit. Due to variations in sign-extension in the code generated by nir_opt_algebraic.py, this meant that nir_search doesn't always do what you want. Instead, 32-bit values should be matched as 32-bit and 64-bit values should be matched as 64-bit. While we're here we unify the unsigned and signed paths. Now that we're using the right bit size, they should be the same since the only difference we had before was sign extension. This gets the UE4 bitfield_extract optimization working again. It had stopped working due to the constant 0xff00ff00 getting sign-extended when it shouldn't have.
