Capture __fastfail exceptions on windows

#258

When software call __fastfail, the exception can't be caught
https://github.com/googleprojectzero/winafl/blob/ea5f6b85572980bb2cf636910f622f36906940aa/winafl.c#L728
winafl wraps two functions in kernelbase.dll

for frida fuzzers, I think this can be done in a similar way as winafl,
but for sancov backend fuzzers, we would have to look at what libfuzzer is doing.
