Alan Donovan	d7a9805478	go.tools/pointer: use assignable not identical type predicate in reflect.{Send,SetMapIndex,etc} ... Various reflect operations permit assignability conversions, i.e. their internals behave unlike y=x.(T) which unpacks only those interface values in x that are identical to T. We split typeAssertConstraint y=x.(T) into two constraints: 1) typeFilter, for when T is an interface type and no representation change occurs. 2) unpack, for when T is a concrete type and the payload of the tagged object is extracted. This constraint has an 'exact' parameter indicating whether to use the predicate IsIdentical (for type assertions) or IsAssignable (for reflect operators). + Tests.
