Weak map references can't move because the st_table needs their address
as a key. But, we also need to remove T_NONE from the map so they
aren't reused.

When you change this to true, you may need to add more tests.

This prevents excessive memory growth when a WeakRef
is repeatedly created
* gc.c (define_final0): avoid duplicate blocks
[Bug #10537]
* test/test_weakref.rb (test_repeated_object_leak): new test
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@48820 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* test/test_weakref.rb (test_recycled): retry and find a WeakRef
whose the target is collected, to fix circumstance dependent.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44555 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* test/test_weakref.rb (make_weakref): return single level
WeakRef, instead of multiple level, since the second level
object may be still alive even after the final object get
finalized, in test_recycled.
* test/test_weakref.rb (test_ref): move living object assertions
from test_recycled.

* array.c (rb_ary_delete_same_obj): new function for WeakRef.
This deletes same objects as item argument in the array.
* internal.h (rb_ary_delete_same_obj): add a declaration.
* gc.c (wmap_final_func): remove WeakRef object reference from the
array. rb_ary_delete() is not usable because it uses rb_equal() to
compare object references.
* gc.c (wmap_finalize): remove recycled object references from weak
map hash properly. How to get object reference from object id was
wrong. st_delete() doesn't work properly if key and value arguments
are same. The key of obj2wmap is referenced object and the value of
obj2wmap is WeakRef array.
* gc.c (wmap_aset): obj2wmap should contain WeakRef array in the
definition.
* test/test_weakref.rb
(TestWeakRef#test_not_reference_different_object,
TestWeakRef#test_weakref_finalize): add tests for above.

Revert "Fix finalize of WeakRef"
This causes segv on rubyspec.
