That the symbols are the same each time is a characteristic of what you're doing, not of LLVM itself.  The symbols are only generated for printing, and are not an attribute of the underlying Instruction object.  Running additional optimization passes after a first printing will usually change the generated number, as instructions are removed, reordered, and coalesced.
