John McCall 9890d8bca0 Add swift_dynamicCast. ...

This is the most general dynamic cast operation, permitting
arbitary source and destination types and handling arbitrary
changes in representation.  A value of the destination type
is constructed in an address provided by the caller; flags
control the behavior w.r.t. the source value.

Not yet used; probably buggy in various particulars.
