[Hexagon] Fix the value of HexagonII::TypeCVI_FIRST
This value is the first vector instruction type in numerical order. The
previous value was incorrect, leaving TypeCVI_GATHER outside of the range
for vector instructions. This caused vector .new instructions to be
incorrectly encoded in the presence of gather.
