[RISCV] Use uint16_t instead of unsigned for opcodes in the RVV pseudo instruction table.

We currently have about 7000 opcodes in the RISCVGenInstrInfo.inc
enum. We can use uint16_t to store these values. We would need to
grow by nearly 9x before we run out of space so this should last
for a little while.

This reduces the llc binary by 32K.
