* Refactor `PtcInfo` This change reduces the coupling of `PtcInfo` by moving relocation tracking to the backend. `RelocEntry`s remains as `RelocEntry`s through out the pipeline until it actually needs to be written to the PTC streams. Keeping this representation makes inspecting and manipulating relocations after compilations less painful. This is something I needed to do to patch relocations to 0 to diff dumps. Contributes to #1125. * Turn `Symbol` & `RelocInfo` into readonly structs * Add documentation to `CompiledFunction` * Remove `Compiler.Compile<T>` Remove `Compiler.Compile<T>` and replace it by `Map<T>` of the `CompiledFunction` returned.
