Move TupleTableSlots boolean member into one flag variable.
There's several reasons for this change:1) It reduces the total size of TupleTableSlot / reduces alignment padding, making the commonly accessed members fit into a single cacheline (but we currently do not force proper alignment, so that's not yet guaranteed to be helpful)2) Combining the booleans into a flag allows to combine read/writes from memory.3) With the upcoming slot abstraction changes, it allows to have core and extended flags, in a memory efficient way.Author: Ashutosh Bapat and Andres FreundDiscussion:https://postgr.es/m/20180220224318.gw4oe5jadhpmcdnm@alap3.anarazel.de1 parent9d906f1 commitc525734
