Before this change, we had only emitted a SinglePos (GPOS type 1) lookup for a statement like `pos A' B' 20`; after this change, we always emit a chain rule even if there is no context. There is a semantic difference if the rule is preceded by a `ignore pos` statement. Omitting context-free contextual chains was actually not a (premature) optimization, but an artifact that came from the representation of glyph patterns. https://github.com/behdad/fonttools/issues/516
