InfoTransform

trait InfoTransform extends SubComponent with Transform

An InfoTransform contains a compiler phase that transforms trees and symbol infos -- making sure they stay consistent. The symbol info is transformed assuming it is consistent right before this phase. The info transformation is triggered by Symbol::rawInfo, which caches the results in the symbol's type history. This way sym.info (during an enteringPhase(p)) can look up what the symbol's info should look like at the beginning of phase p. (If the transformed info had not been stored yet, rawInfo will compute the info by composing the info-transformers of the most recent phase before p, up to the transformer of the phase right before p.)

Concretely, enteringPhase(p) { sym.info } yields the info *before* phase p has transformed it. Imagine you're a phase and it all makes sense.
