  [clang][bytecode] Replace MoveFn With DtorFn + memcpy (#151717)

First, the old MoveFn was rather inefficient, since the dead data cannot
ever be accessed anyway.

Second, there was a problem where the only reason a block still had a
pointer to it (and thus was made into a DeadBlock instead of simply
being deallocated) as that a nested field in the block pointed to the
block itself.

Fix this by calling the dtor function unconditionally. If the block
*still* has pointers after that, we really need to create a DeadBlock
for it.
