[PATCH] D34629: Add isElementAtomic query method to MemInstrinsic class.

Oh, I see...

What's the advantage of "I->isElementAtomic()" over "isa<ElementUnorderedAtomicMemCpyInst>(I)"?

Not sure it makes sense to make ElementUnorderedAtomicMemCpyInst inherit from MemCpyInst; it's likely to be confusing that a MemCpyInst might not really be a memcpy.
