Long prototype chains are slooooooooow

In parts because we're not caching contextual lookups. But we could look at ways of collapsing the chains where possible. Siren's Reflection capability makes this more of a problem.

... And there's no way to statically detect whether reflection will be used on some particular type or not :/ (or even at all)

[robotlolita]

It's not as bad in Siren because reflection can only happen through the Mirror object. I'll probably add an optimisation flag in the compiler for places where it can't guess through PGO though
