Summary:
r342805 added support for the check-cxx-abilist target on FreeBSD, but broke
the target on macOS in doing so. The problem is that the GENERIC_TARGET_TRIPLE
gets overwritten after replacing the FreeBSD regular expression, which
nullifies the replacement done with the darwin regular expression.

numbers off of freebsd target triples, when generating the name of the
ABI list file for check-cxx-abilist target.
Also remove unnecessary parentheses in the regex for darwin, and
slightly reword the comment.

Summary:
Currently, the ABI list test only works for ABI version 1. This commit
allows running the ABI list test with ABI version 2. It also adds an
ABI list file for ABI v2 on Mac OS X.

r333467 updated the symbols exported by libc++.so/dylib by changing
the ODR usage of __uncaught_exception/__uncaught_exceptions. This
should not be a breaking change.

Libc++ frequently creates and uses utilities written in python.
Currently there are python modules under both libcxx/test and
libcxx/util. My goal with these changes is to consolidate them
into a single package under libcxx/utils/libcxx.

The check-cxx-abilist rule uses TARGET_TRIPLE to determine which
ABI list to check. However the triple on Apple contains the darwin
version which changes frequently, but libc++ doesn't need
different ABI lists for each darwin version.
This patch strips the minor version and patchlevel from TARGET_TRIPLE
before using it to determine the ABI list.

This patch re-commits a previous attempt to support building libc++ w/o
an ABI library. That patch was originally reverted because:
1) It forgot to teach the test suite about "default" ABI libraries.
2) Some LLVM builders don't clear the CMake cache between builds. The previous
patch caused those builders to fail since their old cache entry for
LIBCXX_CXX_ABI="" is no longer valid.
The updated patch addresses both issues. It works around (2) by adding
a hack to force the builders to update their cache entries. The hack will
be removed shortly once all LLVM builders have run.
Original commit message
-----------------------
Typically libc++ uses libc++abi or libcxxrt to provide the ABI and runtime bits
of the C++ STL. However we also support building w/o an ABI library entirely.
This patch fixes building libc++ w/o an ABI library (and incorporates the
`~type_info()` fix in D28211).
The main changes in this patch are:
1) Add `-DLIBCXX_CXX_ABI=default` instead of using the empty string to mean "default".
2) Fix CMake bits which treated "none" as "default" on OS X.
3) Teach the source files to respect `-D_LIBCPP_BUILDING_HAS_NO_ABI_LIBRARY`.
4) Define ~type_info() when _LIBCPP_BUILDING_HAS_NO_ABI_LIBRARY is defined.
Unfortunately this patch doesn't help clean up the macro mess that we use to
configure for different ABI libraries.

Currently sym_check almost all names found in the binary, including those
which are defined in other libraries. This makes our ABI lists harder to maintain.
This patch adds a --only-stdlib-symbols option to sym_check which removes
all symbols which aren't possibly provided by libc++. It also re-generates
the linux ABI list after making this change.

This patch adds a `check-cxx-abilist` target which verifies the libc++.so ABI
when the current build configuration matches the configuration used to generate
the ABI lists.
In order to make this change `HandleOutOfTreeLLVM.cmake` needed to be modified
to include `LLVMConfig.cmake` so that `TARGET_TRIPLE` is defined. Hopefully
the changes needed to accommodate this won't break existing build
configurations.
