What is Optimize Shift Operations in DAG about?

The function good_2_LowerShifts expands non-constant shift operations into loops for a given SDValue operation in a SelectionDAG. It handles different shift opcodes (SHL, SRA, SRL) and optimizes right shifts by incorporating a special case for SRL. The function ultimately returns a modified SDValue representing the result of the shift operations.
