Add a new CMake function (``add_libfuzzer_test()``) to simplify
declaration of executables for testing LibFuzzer and use it to
reorganise how tests are declared.
Note that configuration of the lit configuration files has been moved
as late as possible because we are going to need to disable some tests
for some platforms and we will need to propagate this information into
the lit configuration.
Note the code for custom mains was removed because no tests are
currently written for this and Kostya seems happy to remove this.

Previously CMake would successfully configure and compile (with warnings
about ``-fsanitize-coverage=...`` being unused) but the tests LibFuzzer
tests would fail.

Previously the flags were only being set correctly when the
build type was "Release". Now the build should work properly
for all the supported build types. When building libFuzzer
the optimization level respects whatever is used for the
rest of LLVM but for the LibFuzzer tests we force -O0.

The ``nprocs`` command does not exist under Mac OSX so use
``sysctl`` instead on that platform.
Whilst I'm here
* Use ``pclose()`` instead of ``fclose()`` which the ``popen()``
documentation says should be used.
* Check for errors that were previously unhandled.

Work around crashes in ``__sanitizer_malloc_hook()`` under Mac OSX.
Under Mac OSX we intercept calls to malloc before thread local
storage is initialised leading to a crash when accessing
``AllocTracer``. To workaround this ``AllocTracer`` is only accessed
in the hook under Linux. For symmetry ``__sanitizer_free_hook()``
is also modified in the same way.
To support this change a set of new macros
LIBFUZZER_LINUX and LIBFUZZER_APPLE has been defined which can be
used to check the target being compiled for.

It is now less state-dependent and will allow easier comparing of
coverages of different units.

Removed some unused headers, replaced some headers with forward class declarations.
Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'
