- Added the getExtendedGatherOpcode() function, which returns a signed gather load opcode (e.g GLD1_MERGE_ZERO -> GLD1S_MERGE_ZERO)
- Get the extension type of the gather load in LowerMGATHER and use the signed gather opcode returned by getExtendedGatherOpcode() if the extension type is EXTLOAD/SEXTLOAD,
