JIT checks finalizable property for an object only for inlining of
allocation helpers.
If object is finalizable the allocation helper is not inlined and usual VM
helper is called.
This is all what JIT does for finalizable objects today. Usual VM helper
must check finalizable property by itself. Today this check is done inside
of GC_CC - fast_alloc fails if object is finalizable so VM have to call
