SI-6692 pickle one more flag bit: EXISTENTIAL
before, PickledFlags & EXISTENTIAL == 0, so that an existential symbol would lose the EXISTENTIAL bit when pickled, causing spurious incremental recompiles, as pickled information and type-checking-from-source-based information differed pickling this additional bit should be a compatible change, as older versions (pre-2.9.3) will simply mask out the extra flag bits pickled as of now (2.9.3) so that their behavior is not affected -- newer versions will see more flags, which might cause regressions, but it's also the only way to fix SI-6692 this obviates the need to set the existential flag when unpickling an existential type's params this is the smallest backport of a9b85db and 3e2c31f that I could think of as 2.9 is in maintenance mode, I don't want to invest in testing infrastructure to test the pickler, however, the fix is tested by the incremental compiler test 'inc-pickled-existential' in sbt
