e396dab0 - [RISCV] Use SignExtend64<32> instead of ORing in 32 1s into upper bits in RISCVMatInt. NFC (#159864)

[RISCV] Use SignExtend64<32> instead of ORing in 32 1s into upper bits in RISCVMatInt. NFC (#159864) I think this better reflects the intent of modification. In all these places we know bit 31 is 1 so we are sign extending.
