SIL type lowering erases DynamicSelfType, so we generate incorrect code when casting to DynamicSelfType. Fixing this requires a fair amount of plumbing, but most of the changes are mechanical. Note that the textual SIL syntax for casts has changed slightly; the target type is now a formal type without a '$', not a SIL type. Also, the unconditional_checked_cast_value and checked_cast_value_br instructions now take the _source_ formal type as well, just like the *_addr forms they are intended to replace.
