* split the `PassContext` into multiple protocols and structs: `Context`, `MutatingContext`, `FunctionPassContext` and `SimplifyContext` * change how instruction passes work: implement the `simplify` function in conformance to `SILCombineSimplifyable` * add a mechanism to add a callback for inserted instructions
