Kostya Serebryany 20bb5e71b2 [libFuzzer] make LLVMFuzzerTestOneInput (the fuzzer target function) return int instead of void. The actual return value is not *yet* used (and expected to be 0). This change is API breaking, so the fuzzers will need to be updated.

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.
