Lower intrinsics calls: forget, size_of, unreachable, wrapping_*
This allows constant propagation to evaluate `size_of` and `wrapping_*`, and unreachable propagation to propagate a call to `unreachable`. The lowering is performed as a MIR optimization, rather than during MIR building to preserve the special status of intrinsics with respect to unsafety checks and promotion.
