Port libFuzzer tests to LIT. Do not require two-stage build for check-fuzzer.
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.
