  Fix memory leak in singleton_object_pool (#835)

Two memory leak fixes related singleton_object_pool.

    1. The singleon_object_pool currently only destructs objects but does not deallocate memory space. This leak applies to all architectures.

    2. On ppc and arm, instruction decoder does not use smart pointers to manage InstructionAPI::Instruction constructed by a singleon_object_pool, and thus cause memory leaks.
