This adds support for instruction iterators, as well as rewriting the builder code to use these new functions. This lets us eliminate the C bindings for moving around the builder. Patch by Erick Tryzelaar! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48774 91177308-0d34-0410-b5e6-96231b3b80d8
