IRGen: Emit SIL destructors. Emit the SIL destructor as a destroying destructor, then emit a deallocating destructor shim that calls into it and then returns the heap size. (The actual deallocation still happens in swift_release--I talked to John about that and I'll fix it later.) This gets the broken SIL/IRGen class tests passing again. Swift SVN r3838
