[Truffle] Support for long[]/double[] in TypeSystem

[Chris Seaton]

Hi Stefan,

I’m not sure about your specific error, but if you want to hear about how I applied storage strategies in Ruby catch me on Skype. We never wrote it up but I think we did some interesting work.

I basically applied something like CF Bolz’s work, but instead of a strategy singleton the node itself kind of fulfils that role. And at the moment I’m detecting the strategy from the storage object type, not by any extra field in the object.

Or are you planning something new unrelated to the PyPy approach?
