This fixes an inconsistency where the type for nil in code such as var x unsafe.Pointer = nil and in conversions of the form T(nil) (where T is a pointer, function, slice, map, channel, interface, or unsafe.Pointer) was reported as (converted to) the respective type. For all other operations that accept a nil value, we don't do this conversion for nil. (We never change the type of the untyped nil value, in contrast to other untyped values where we give the values context-specific types.) It may still be useful to change this behavior and - consistently - report a converted nil type like we do for any other type, but for now this CL simply fixes the existing inconsistency. Added tests and fixed existing test harness. Updates #13061.
