Stephen Tozer 14b62f7e2f [DebugInfo] CGP+HWasan: Handle dbg.values with duplicate location ops ... This patch fixes an issue which occurred in CodeGenPrepare and HWAddressSanitizer, which both at some point create a map of Old->New instructions and update dbg.value uses of these. They did this by iterating over the dbg.value's location operands, and if an instance of the old instruction was found, replaceVariableLocationOp would be called on that dbg.value. This would cause an error if the same operand appeared multiple times as a location operand, as the first call to replaceVariableLocationOp would update all uses of the old instruction, invalidating the old iterator and eventually hitting an assertion. This has been fixed by no longer iterating over the dbg.value's location operands directly, but by first collecting them into a set and then iterating over that, ensuring that we never attempt to replace a duplicated operand multiple times.
