title: In LLVM IR, how can I print the name of a unnamed value which is represented as an unsigned numeric value with their prefix such as %2?
body: <p>I want to print out the instructions written in LLVM IR( for practice ) and I have a BitCastInst like this: 
      <code>%0 = bitcast [32xi32]* %reg to i8*</code></p>
  
  <p>How can I print its name of left value which is a unnamed value <code>%0</code> in this case?</p>
