Summary: To maintain compatibility with GAS, we need to stop treating negative 32-bit immediates as 64-bit values when expanding LI/DLI. This currently happens because of sign extension. To do this we need to choose the 32-bit value expansion for values which use their upper 33 bits only for sign extension (i.e. no 0's, only 1's).
