Reduce flag fiddling

There isn't much point to the late* flags in a world where
we're mutating flags left and right in tree and info transformers...

So, lets get rid of the indirection until we can include flags
in a symbol's type history, like we do for its info.

This retires lateDEFERRED (redundant with SYNTHESIZE_IMPL_IN_SUBCLASS).
Since it's introduced so late, it makes little sense to have these
synthetic members go back to DEFERRED. Instead, just set DEFERRED directly.

Also remove unused late* and not* flags.
notPRIVATE subsumes lateFINAL for effective finality (scala/scala-dev#126)
