  Log Message:
  -----------
  [flang][OpenACC] Add minus operator to reduction clause (#200909)

Adds '-' as a recognized reduction operator alongside '+'. The new
ReductionOperator::Operator::Minus is parsed from the '-' token,
accepted on integer/real/complex reduction variables, and lowered the
same as Plus (mlir::acc::ReductionOperator::AccAdd in OpenACC, and
fir::ReduceOperationEnum::Add in DO CONCURRENT). The unparser emits it
as '-'.
