Aaron Ballman 7b54ed221a Temporarily reverting the fuzzer library as it causes too many build issues for MSVC users. This reverts: 227445, 227395, 227389, 227357, 227254, 227252

Kostya Serebryany d53b43fe11 Add a Fuzzer library 
Summary:
A simple genetic in-process coverage-guided fuzz testing library.

I've used this fuzzer to test clang-format
(it found 12+ bugs, thanks djasper@ for the fixes!)
and it may also help us test other parts of LLVM.
So why not keep it in the LLVM repository?

I plan to add the cmake build rules later (in a separate patch, if that's ok)
and also add a clang-format-fuzzer target.

See README.txt for details.

Test Plan: Tests will follow separately.
