MethodHandles::lookup produces a Lookup object on the caller class. The
original intention for a Lookup object whose lookup class is always a
non-array and non-primitive class.
MethodHandles::privateLookupIn and Lookup::in are the two other ways
that can produce a new Lookup object and they should disallow the new
lookup class be a primitive or array class.
This patch proposes to make Lookup::in consistent with
MethodHandles::privateLookupIn to throw IAE if the target class is an
array type or primitive type.
