FuzzerExtFunctionsWeakAlias.cpp
Summary:
Replace FuzzerExtFunctionsDlsymWin.cpp with FuzzerExtFunctionsWeakAlias.cpp
to get externally defined functions (eg: LLVMFuzzerInitialize,
LLVMFuzzerCustomMutator, etc) working again.
Also enable tests that depended on these functions (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).

Keeping fuzzer.test together as a gigantic test has no advantages and multiple disadvantages:
- Worse test parallelization (fuzzer.test is always blocking the test
run on a machine with many cores)
- Debugging test failures is made more difficult (not clear what fails
from fuzzer.test failing)
- Makes porting tests to new platforms more difficult (whenever
fuzzer.test fails have to inspect the output to figure out what is going
on, and then restart all of it)
- Hides dead code (in our case, "Done1000000" FileCheck variable was
never used, DISABLED: not %t-UninstrumentedTest-Uninstrumented was never
compiled, and there was small amount of duplication vs. simple-cmp.test)
- Makes correspondence between LIT .test files and .cpp files less
straightforward
