59d2dad59e On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics,
so don't claim they are.  They are allocated using DAG.getNode, so attempts
to access MemSDNode fields results in reading off the end of the allocated
memory.  This fixes crashes with "llc -debug" due to debug code trying to
print MemSDNode fields for these barrier nodes (since the crashes are not
deterministic, use valgrind to see this).  Add some nasty checking to try
to catch this kind of thing in the future.

b9e6fe1e3a Removing the useless test that I added recently. It was meant as an example, but not complicated enough to merit another test.

ddd0e65dba Detemplatize NodeRef.
It is now possible to navigate the B+-tree using NodeRef::subtree() and
NodeRef::size() without knowing the key and value template types used in the
tree.
