[libFuzzer] Enable tests on Windows Summary: Enable tests on Windows and make check-fuzzer pass on it. Make check-fuzzer pass on Windows by fixing libFuzzer, fixing tests, and by disabling tests on Windows. Most of these are disabled temporarily as support for the tests and the features they test will be added incrementally. Other tests will not be enabled since they require things that are not on Windows (eg: afl_driver tests). Every test that was explicitly disabled on Windows has a comment explaining why (unless obvious like merge-posix.test). The lit.cfg file was modified to support running tests on windows. fuzzer-dirs.test was fixed by making the Windows implementation print the same error message as the posix version. merge-control-file.test was fixed by making the test binary end with the ".exe" extension (on all platforms).

# FIXME: Disabled on Windows because -fPIC cannot be used to compile for Windows.
[libFuzzer] Generalize the code for getting the previous offset for different architectures Without this change, tests in coverage.test and dump_coverage.test are failing on non-x86_64 platforms. The diff is copied from sanitizer_common library, an alternative would be to link it together with libFuzzer. Differential Revision: https://reviews.llvm.org/D53040 llvm-svn: 344104
