`CallBase` class rather than `CallSite` wrappers. I pushed this change down through most of the statepoint infrastructure, completely removing the use of CallSite where I could reasonably do so. I ended up making a couple of cut-points: generic call handling (instcombine, TLI, SDAG). As soon as it hit truly generic handling with users outside the immediate code, I simply transitioned into or out of a `CallSite` to make this a reasonable sized chunk.
