[llvm-dev] LibFuzzer and platforms availability

[Kostya Serebryany via llvm-dev]

r247321 refactors the code so that it should build on Mac.
I haven't actually tested it on Mac -- so please help me and send follow up
patches if needed.

check-fuzzer will still fail because some of the libFuzzer tests require
dfsan.
I'd use some help from someone with a Mac to modify
lib/Fuzzer/test/CMakeLists.txt so that it does not run dfsan-dependent
tests on Mac.

Thanks,

--kcc
