George Karpenkov f28523bb3f [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.

Matt Morehouse 24568789c4 [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).

Resulting library binaries will be named libclang_rt.fuzzer*, and will
be placed in Clang toolchain, allowing redistribution.
