Not any of the ones I have worked on, nor the ones I know about: they all use hand-written parsers. In practice, error reporting and recovery tends to be tedious and/or difficult with a generated parser, which is a serious issue for practical tools.

Parsing has turned out to be simpler, in practice, than the computing pioneers expected it to be, because simpler grammars are easier for both machines and humans to reason about. Instead of using sophisticated parser generators, we just design dumb grammars: that works out better all around.
