Revert "Fix compiler-rt build on Windows after D89640"
This reverts commit a7acee89d6.
This reverts commit d09b08919c.
Reason: breaks Linux / x86_64 build.
Summary: This patch separates platform related macros in lib/fuzzer/FuzzerDefs.h into lib/fuzzer/FuzzerPlatform.h, and use FuzzerPlatform.h where necessary. This separation helps when compiling libFuzzer's interceptor module (under review); an unnecessary include of standard headers (such as string.h) may produce conflicts/ambiguation with the interceptor's declarations/definitions of library functions, which complicates interceptor implementation.

Summary:
Add basic support for emscripten.
This enables libFuzzer to build (using build.sh) for emscripten and fuzz
a target compiled with
-fsanitize-coverage=inline-8bit-counters.
Basic fuzzing and bug finding work with this commit.
RSS limit and timeouts will not work because they depend on system
functions that are not implemented/widely supported in emscripten.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
This patch adds the initial support for Fuchsia.
- LIBFUZZER_FUCHSIA is added as an OS type in FuzzerDefs.h
- Fuchsia is, by design, not POSIX compliant. However, it does use ELF and
supports common POSIX I/O functions. Thus, FuzzerExtFunctions.h and
FuzzerIO.h are implemented by extending the header guards in
FuzzerExtFunctionsWeak.cpp and FuzzerIOPosix.cpp to include
LIBFUZZER_FUCHSIA.
- The platform-specific portions of FuzzerUtil.h are implemented by
FuzzerUtilFuchsia.cpp, which makes use of exception ports, syscalls, and
the launchpad library.
- The experimental equivalence server is not currently supported, so
FuzzerShmem.h is implemented by stub methods in FuzzerShmemFuchsia.cpp.
Any future implementation will likely involve VMOs.
Tested with ASAN/SanCov on Fuchsia/x86-64 with the canonical toy fuzzer.

Summary:
This code already works and passes some number of tests.
There is need to finish remaining sanitizers to get better coverage.
Many tests fail due to overly long file names of executables (>31).
This is a current shortcoming of the NetBSD 8(beta) kernel, as
certain functions can fail (like retrieving file name of executable).
