Since Put() makes a dynamic function call, this CL includes a long-overdue change to supply a *frame (and thus the call
stack and the interpreter) to intrinsics too.
This fixes the tests that were broken by (sound) revision e4a4cb47c141.

CL 49530047 made the (over-)simplifying assumption that the
Path of an ad-hoc (Created) package should default to its
Name, i.e. package declaration.
With this change, the Name is still always computed from the
package declaration (by go/types) but the Path may be
specified by the loader.Config. If "", the value of the Name
is used, which is not globally unique.
