c5917e5476 Re-apply "Introduce FuzzMutate library"
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.

f20e6862f6 Revert "Re-apply "Introduce FuzzMutate library""
The dependencies for the new library seem to be misconfigured on some
linux configs:

This reverts r311392.

4ecbed71c1 Re-apply "Introduce FuzzMutate library"
Redo r311356 with a fix to avoid std::uniform_int_distribution<bool>.
The bool specialization is undefined according to the standard, even
though libc++ seems to have it.

Looks like this fails to build with libstdc++.

This reverts r311356

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