Allow interrupting GetMultiXactIdMembers
This function has a loop which can lead to uninterruptible process"stalls" (actually infinite loops) when some bugs are triggered. Avoidthat unpleasant situation by adding a check for interrupts in a placethat shouldn't degrade performance in the normal case.Backpatch to 9.3. Older branches have an identical loop here, but theaforementioned bugs are only a problem starting in 9.3 so there doesn'tseem to be any point in backpatching any further.
