vect: Add missed opcodes in vect_get_smallest_scalar_type [PR115228]
Some opcodes are missed when determining the smallest scalar type for a
vectorizable statement. Currently, this bug does not cause any problem,
because vect_get_smallest_scalar_type is only used to compute max nunits
vectype, and even statement with missed opcode is incorrectly bypassed,
the max nunits vectype could also be rightly deduced from def statements
for operands of the statement.
In the future, if this function will be called to do other thing, we may
get something wrong. So fix it in this patch.
