Same as r311392 with some fixes for library dependencies. Thanks to Chapuni for helping work those out! Original commit message: This introduces the FuzzMutate library, which provides structured fuzzing for LLVM IR, as described in my EuroLLVM 2017 talk. Most of the basic mutators to inject and delete IR are provided, with support for most basic operations. llvm-svn: 311402
