In rare cases we can receive request to inject into completelly empty basic block. In the normal case
all basic blocks contain at least terminator instruction, but it is possible that the only instruction is
catchpad instruction which is not part of the instruction iterator. This case seems rare enough to not care
about it.
Submiting without review, since it seems almost NFC. I couldn't come up with any reasonable way to test this.

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.

The dependencies for the new library seem to be misconfigured on some
linux configs:

This reverts r311392.

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.
