I just found the Interval class, and it looks like it could help me out 
here. I want to locate the Interval that begins with the call to the 
"magic" begin(), and ends with the call to the "magic" end(), if it 
exists. If there is no such valid interval, then I want to detect that 
and return an error. Can I make this happen by using the 
IntervalPartition pass? It looks like LLVM has some functionality that 
I could use *some where.* I just can't quite figure out how to make use 
of it.
