Reid Spencer c32e0fedab For PR1113: 
Increment the counter after the second use, not after the first use. This
fixes PR1113.

Also, rename some classes for simplicity and to more naturally be
reminscient of LLVM 1.9. This in preparation for additional classes that
will provide a scaled down model of the LLVM 1.9 IR.
