To rephrase, you want to instrument a program so that, when you run it, 
it computes the number of instructions executed at run-time.  Is this 
correct?

By number of instructions, do you mean LLVM instructions or native code 
instructions?

Have you read the documentation from the web site:

How to Write an LLVM Pass
LLVM Programmer's Manual
LLVM Language Reference Manual (you just need to skim it to get a basic 
understanding of what the IR looks like)
