Standard libraries may (libstdc++ in particular) forbid direct use of
assert()/<cassert> in library code.

The fix affects follow algorithms:
remove_if, unique, rotate, inplace_merge, partial_sort_copy, set_union, set_intersection, set_difference, set_symmetric_difference.
For "is_trivial" types there are no problems with "creating objects/clean-up"
For non-trivial types the algo results are also correct, but possible incorrect copying/moving "operator=" calls "by raw memory" within one of mentioned algo or incorrect destructor calls in the end of algo.
It fixes an ambiguity issue in case of a user has a custom policy and
calls a version of exclusive_scan with binary operation.

Summary:
This commit allows specifying LIBCXX_ENABLE_PARALLEL_ALGORITHMS when
configuring libc++ in CMake. When that option is enabled, libc++ will
assume that the PSTL can be found somewhere on the CMake module path,
and it will provide the C++17 parallel algorithms based on the PSTL
(that is assumed to be available).
The commit also adds support for running the PSTL tests as part of
the libc++ test suite.
The first attempt to commit this failed because it exposed a bug in the
tests for modules. Now that this has been fixed, it should be safe to
commit this.

This reverts r366593, which caused unforeseen breakage on the build bots.
I'm reverting until the problems have been figured out and fixed.

Mostly unused parameter, unused local typedefs and shadowed declarations.
This massaging it necessary if we want to be able to run the tests under
the libc++ lit configuration.

- unused parameter warnings
- don't use single-letter template parameter names, like we do in libc++
- sign-comparison warnings
- unused variables in the tests
- unused local typedefs in the tests
- the use of #include_next
- field reordering in the tests
- unused lambda captures
Note that the rationale for why the static_casts to unsigned are OK is
that last - first must always be non-negative, since [first, last) is
a valid range.

Summary:
PSTL should not provide those headers since they belong to the standard
library. Instead, we define a dummy standard library in the tests that
provides those headers.

Necessary when pstl is included from with <algorithm> and <numeric> to
prevent a partially declared standard library when pstl itself uses
algorithms from <algorithm> and <numeric>.
Also, this patch makes sure that configuration comes via standard headers.
Directly including pstl_config.h in implementation files is incompatible
with inclusion of pstl into a standard library implementation which
provides it's own library wide configuration and may configure the
library differently to the pstl_config.h used by the standalone
implementation.
