You could check whether the operand is a getelementptr instruction. This 
would indicate either an array or structure access but you could 
distinguish those based on the type of the accessed value. If you want 
to link the access to a particular array and subscript in the original 
source code, you might want to hack Clang to add this as metadata on the 
instruction (assuming your IR comes from C/C++ code).
