cef6ef9a84 SIL: add a debug_step instruction 
This instruction can be inserted by Onone optimizations as a replacement for deleted instructions to
ensure that it's possible to single step on its location.

cc68bd98c9 Swift Optimizer: rework pass context types and instruction passes 
* 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

3b43da9637 Swift Optimizer: improve ergonomics of Builder and PassContext 
* split the PassUtils.swift file into PassContext.swift and Passes.swift
* rework `Builder` bridging allowing more insertion point variations, e.g. inserting at the end of a block.
* add Builder.create functions for more instructions
* add `PassContext.splitBlock`
* move SIL modification functions from PassContext to extensions of the relevant types (e.g. instructions).
* rename `Location.bridgedLocation` -> `Location.bridged`
