This introduces the FuzzMutate library, which provides structured fuzzing for LLVM IR, as described in my EuroLLVM 2017 talk <http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#2>. Most of the basic mutators to inject and delete IR are provided, with support for most basic operations.

I will follow up with the instruction selection fuzzer, which is implemented in terms of this library.
