Kostya Serebryany 1d7a33b8ae [libFuzzer] remove the now redundant 'LLVMFuzzer-' prefix from libFuzzer tests
llvm-svn: 310110

George Karpenkov 8ecdd7be15 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.

Kostya Serebryany 1ca738809a [libFuzzer] experimental feature -reduce_inputs (off by default) that tries to replace elements in the corpus with smaller ones that have the same feature set. Still needs tuning
