  -----------
  [TableGen][Decoder] Remove special case of single sub-op dag (#156175)

If a custom operand has MIOperandInfo with >= 2 sub-operands, it is
required that either the operand or its sub-operands have a decoder
method (depending on usage). Require this for single sub-operand
operands as well, since there is no good reason not to.
