Toma Tabacu 039eb5a7b8 [mips] [IAS] Fix expansion of negative 32-bit immediates for LI/DLI. 
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).
