76f452e9 - [flang] Keep switch successor operand counts in sync (#234126)

[flang] Keep switch successor operand counts in sync (#234126) FIR switch operations fail to update target_operand_offsets when successor operands are added or removed through MutableOperandRange. Declare the attribute in ODS so it can be updated by setInherentAttr, which MutableOperandRange has used since ad9dc60252ed (#218907). Add regression tests for operand insertion and removal.
