Louis Dionne 79ee0342db [runtimes] Always define cxx_shared, cxx_static & other targets
However, mark them as EXCLUDE_FROM_ALL when we don't want to build them.
Simply declaring the targets should be of no harm, and it allows other
projects to mention these targets regardless of whether they end up
being built or not.

While the diff may not make that obvious, this patch basically
moves the definition of e.g. `cxx_shared` out of the `if (LIBCXX_ENABLE_SHARED)`
and instead marks it as `EXCLUDE_FROM_ALL` conditionally on whether
LIBCXX_ENABLE_SHARED is passed. It then does the same for libunwind
and libc++abi targets.

Arthur O'Dwyer 243da90ea5 [libc++] Add the C++17 <memory_resource> header (mono-patch)
This patch is the rebase and squash of three earlier patches.
It supersedes all three of them.

- D47111: experimental monotonic_buffer_resource.
- D47358: experimental pool resources.
- D47360: Copy std::experimental::pmr to std::pmr.

The significant difference between this patch and the-sum-of-those-three
is that this patch does not add `std::experimental::pmr::monotonic_buffer_resource`
and so on. This patch simply adds the C++17 standard facilities, and
leaves the `std::experimental` namespace entirely alone.

Mark de Wever a1beb0a382 [libc++][format] Implements formattable concept.
This concept is introduced in P2286, but was implemented in libc++
before. This implementation was used in the library internally. This
implementation lacked the resolution of LWG3636. The original formatter
had a non-const member function that wasn't trivial to make a const
member. The recent parser improvements made this member a const member
in preparation of LWG3636.

Note LWG3636 isn't voted in. Its status is Ready. P2286's concept has
been written as-if LWG3636 is accepted and refers to that LWG issue.

Updates some tests make format a const member function and removes a
tests that's mainly a duplicate of the formattable concept test.

Implements
- LWG3636 formatter<T>::format should be const-qualified

Implements parts of

Louis Dionne 258477ed0a [llvm] Remove libcxx, libcxxabi and libunwind from supported LLVM_ENABLE_PROJECTS
This is a breaking change. If you were passing one of those three runtimes
in LLVM_ENABLE_PROJECTS, you need to start passing them in LLVM_ENABLE_RUNTIMES
instead. The runtimes in LLVM_ENABLE_RUNTIMES will start being built using
the "bootstrapping build" instead, which means that they will be built
using the just-built Clang. This is usually what you wanted anyway.

If you were using LLVM_ENABLE_PROJECTS=all with the explicit goal of
building these three runtimes, you can now use LLVM_ENABLE_RUNTIMES=all
and these runtimes will be built using the bootstrapping build.

NOTE: This is a re-application of 887b8bd733 which had been reverted
      in 6b03a4fea0 because it broke the Sphinx documentation publishers.
      The Sphinx documentation publishers have now been moved to using
      the runtimes build, so this should not be an issue anymore.

Zibi Sarbinowski 36dde913b0 [SystemZ][z/OS] Add ASCII and 32-bit variants for libc++.
This patch enables libc++ build as shared library in all combinations of ASCII/EBCDIC and 32-bit/64-bit variants. In particular it introduces:

  # ASCII version of libc++ named as libc++_a.so
  # Script to rename DLL name inside the generated side deck
  # Various names for dataset members where DLL libraries and their side decks will reside
  # Add the following options:

   - LIBCXX_SHARED_OUTPUT_NAME
   - LIBCXX_ADDITIONAL_COMPILE_FLAGS
   - LIBCXX_ADDITIONAL_LIBRARIES
   - LIBCXXABI_ADDITIONAL_COMPILE_FLAGS
   - LIBCXXABI_ADDITIONAL_LIBRARIES

**Background and rational of this patch**

The linker on z/OS creates a list of exported symbols in a file called side deck. The list contains the symbol name as well as the name of the DLL which implements the symbol. The name of the DLL depends on what is specified in the -o command line option. If it points to a USS file, than the DLL name in the side deck will be the USS file name. If it points to a member of a dataset then the DLL name in the side deck is the member name.

If CMake could deal with z/OS datasets we could use -o that points to a dataset member name, but this does not seem to work so we have to produce a USS file as the DLL and then copy the content of the produced side deck to a dataset as well as rename the USS file name in the side deck to a dataset member name that corresponds to that DLL.
