The filesystem tests were expecting the paths to the build/source directories
did not contain any symlinks. This patch resolves those symlinks before running
the test suite.

Single threaded builds often don't provide a monotonic clock, so we can't
always provide a monotonic SleepFor(...) implementation. Hopefully this
won't cause the builds to hang.

This patch fixes the following bugs, all of which were discovered while
testing a 32 bit build on a 64 bit machine.
* path.itr/iterator.pass.cpp has undefined behavior.
'path::iterator' stashes the value of the element inside the iterator.
This violates the BiDirIterator requirements but is allowed for path::iterator.
However this means that using reverse_iterator<path::iterator> has undefined
behavior because it assumes that 'Iter tmp = it; return *tmp' will not create
a dangling reference. However it does, and this caused this particular test
to fail.
* path.native.obs/string_alloc.pass.cpp tested the SSO with a long string.
On 32 bit builds std::wstring only has the SSO for strings of size 2. The
test was using a string of size 4.
* fs.op.space/space.pass.cpp had overflows while calculating the expected values.
The fix here is to convert the statvfs data members to std::uintmax_t before
multiplying them. The internal implementation already does this but the tests
needed to do it as well.

Add the completed std::experimental::filesystem implementation and tests.
The implementation supports C++11 or newer.
The TS is built as part of 'libc++experimental.a'. Users of the TS need to
manually link this library. Building and testing the TS can be disabled using
the CMake option '-DLIBCXX_ENABLE_FILESYSTEM=OFF'.
Currently 'libc++experimental.a' is not installed by default. To turn on the
installation of the library use '-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON'.
