This reverts commit 15425f2bc6eac6249ee957a2a280511306c07547.
Should work now that atos is a default symbolizer on Darwin.

Summary:
Implements https://github.com/google/sanitizers/issues/835.
Flush stdout before exiting in test cases.
Since the atexit hook is used for exit reports, pending prints to
stdout can be lost if they aren't flushed before calling exit().
Expect tests to have non-zero exit code if exit() is called.

The optional external function callbacks have to be exported in order
for them to be called. The test was failing because libFuzzer wasn't
calling LLVMFuzzerInitialize.
We can reconsider if this is the best way to mark these optional
callbacks exported later.

This reverts commit 546e006a023cccd0fd32afd442ab992d3515d4b8.
Reverting until I can figure out llvm-symbolizer breakages on mac os.

With this change, libFuzzer will ignore any arguments after a sigil
argument, but it will preserve these arguments at the end of the
command line when launching subprocesses. Using this, its possible to
handle positional and single-dash arguments to the program under test
by discarding everything up to -ignore_remaining_args=1 in
LLVMFuzzerInitialize.

The current code relies on the assumption that tests are included only
if LLVM_USE_SANITIZE_COVERAGE is enabled.
This commit makes it easier to relax the assumption in the future, as
the variable LIBFUZZER_FLAGS_BASE is used further in libFuzzer tests.

The warning is reproducible with GCC 4.8. Thanks to David Blaikie for
the suggested fix.
The reported warning was

This fixes a bug where unmodifiable strings where passed to posix_spawn.
This is an attempt to unbreak the greendragon libFuzzer bot.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).
