[swift-evolution] Specialization of functions with default parameters or discardable result

Functions in Swift can have default parameters or discardable result, but without inlining, calling them could be suboptimal in performance.

I propose a solution which compiler generates specializations of those functions, hence more optimization can be performed for specific usage.

This can also be used to solve binary compatibility when new parameters are added to a function.
