This revision ports all libFuzzer tests apart from the unittest to LIT.
The advantages of doing so include:
- Tests being self-contained
- Much easier debugging of a single test
- No need for using a two-stage compilation
The unit-test is still compiled using CMake, but it does not need a
freshly built compiler.
NOTE: The previous two-stage bot configuration will NOT work, as in the
second stage build LLVM_USE_SANITIZER is set, which disables ASAN from
being built.
Thus bots will be reconfigured in the next few commits.

Summary:
Implements https://github.com/google/sanitizers/issues/835.
Flush stdout before exiting in test cases.
Since the atexit hook is used for exit reports, pending prints to
stdout can be lost if they aren't flushed before calling exit().
Expect tests to have non-zero exit code if exit() is called.

The optional external function callbacks have to be exported in order
for them to be called. The test was failing because libFuzzer wasn't
calling LLVMFuzzerInitialize.
We can reconsider if this is the best way to mark these optional
callbacks exported later.

With this change, libFuzzer will ignore any arguments after a sigil
argument, but it will preserve these arguments at the end of the
command line when launching subprocesses. Using this, its possible to
handle positional and single-dash arguments to the program under test
by discarding everything up to -ignore_remaining_args=1 in
LLVMFuzzerInitialize.
