[PATCH] D38642: [clang-fuzzer] Allow building without coverage instrumentation.

We often suggest to code owners to implement their own dummy main to run fuzz targets as regression tests. 
But for ourselves (LLVM) this recommendations makes less sense since libFuzzer is part of LLVM and we can use it's main directly.
