[Bug #20868] Fix Method#hash to not change after compaction
The hash value of a Method must remain constant after a compaction, otherwise
it may not work as the key in a hash table.
For example:
def a; end
# Need this method here because otherwise the iseq may be on the C stack
# which would get pinned and not move during compaction
def get_hash
method(:a).hash
end
puts get_hash # => 2993401401091578131
GC.verify_compaction_references(expand_heap: true, toward: :empty)
puts get_hash # => -2162775864511574135
