[PATCH] D75365: [AST Matchers] Fix bug in 'optionally' matcher wherein all previous bindings are cleared when all inner matchers fail.

+1 to this fix.

However, regarding `allOf` vs. `anyOf` semantics, since `optionally` always succeeds, is there a difference between the two semantics?

It seems to me that there should be no difference between `allOf(optionally(a), optionally(b))` vs. `anyOf(optionally(a), optionally(b))`.
