[LLVMdev] Instruction::mayWriteToMemory() -- is there a logical equivalent for reads?

[Sarah Thompson]

The Instruction::mayWriteToMemory() member function is quite useful (I'm 
currently writing code that will break up basic blocks at read/write 
instructions). Is there a safe way to do the same thing for reads from 
memory? It's easy enough to check for the relevant instructions, but I 
thought this might be a nice-to-have in a future version because it 
separates code like mine from needing to know too much about the 
instructions it is manipulating (which is a good thing from a future 
portability point of view, as well as being logically cleaner).
