Title: a follow up on e01ec05a1e

Removes all traces of flags from symbol API, adds general flag set (hasFlag)
to Modifiers (because Modifiers don't have isXXX checks that symbols have).

This also removes macros.Symbol.setFlags, because taking into account current
state of affairs that method was at best incomplete.
