Optimizations

[akovari]

• [x] ~~tuples represented as arrays of objects~~ (this wouldn't allow for specific tuple extensions such as FileTuple)
• [x] rewrite BinaryOperationNode using Specialization
• [ ] see if operations with constants can be be calculated in the parser (1 +2)
• [x] check lambda lifting. Lift lambdas into non-closures unless necessary, so stack doesn't have to be restored when it is pure function
• [ ] check if lambdas capture any variables, if not, avoid materializing stack
• [x] avoid using java collections in pattern matching
• [x] allow let expression to be truly concurrent
• [ ] make sure promises are unwrapped whenever possible before calling map
• [ ] see if TruffleBoundary can be removed from FrameSlotAliasNode and FrameSlotAliasNode and AnyValueNode
• [ ] make module/function cache indexed by Seq, not String
• [ ] cache resolved dependencies in the PatternLetNode
