Add a target_info definition for NetBSD. The definition is based
on the one used by FreeBSD, with libcxxrt replaced by libc++abi,
and using llvm-libunwind since we need to use its unwinder
implementation to build anyway.
Additionally, XFAIL the 30 tests that fail because of non-implemented
locale features. According to the manual, NetBSD implements only
LC_CTYPE part of locale handling. However, there is a locale database
in the system and locale specifications are validated against it,
so it makes sense to list the common locales as supported.
If I'm counting correctly, this change enables additional 43 passing
tests.

Otherwise, even specifying a runtime root different from the library
we're linking against won't work -- the library we're linking against
is always used. This is undesirable if we try testing something like
linking against a recent libc++.dylib but running the tests against an
older version (the back-deployment use case).

Summary:
The result of subprocess.check_output() is bytes in python3 which we need
to convert to str(). Simplify this by using the executeCommand() helper.

On some platforms clock_gettime is in librt, which we don't
link by default when building the tests. However it is required
by the filesystem tests.
This patch introduces a workaround which links librt whenever
the filesystem tests are enabled. The workaround should later
be replaced with a patch that selectively links both libc++fs
and librt only when building filesystem specific tests. However,
the way the test configuration is set up right now, this is
non-trivial.

On Apple the test feature 'sanitizer-new-delete' was incorrectly
getting added to the LIT feature set, which mistakenly caused tests
to be disabled when using UBSAN (the feature is only needed with ASAN/MSAN/TSAN).

Summary:
This reference to lit.util.capture is functionally identical to
subprocess.check_output, so this change switches to call the library routine
directly.

As we're trying to setup testing / bots for all shipping version of libc++
on macOS/iOS, we'll need to be able to pass a path to where to find the
dylib for each previous version of the OS.

The tests for libc++ specify -target on the command-line to the
compiler, but this is problematic for a few reasons.
Firstly, the -target option isn't supported on Apple platforms. Parts
of the triple get dropped and ignored. Instead, software should be
compiled with a combination of the -arch and -m<name>-version-min
options.
Secondly, the generic "darwin" target references a kernel version
instead of a platform version. Each platform has its own independent
versions (with different versions of libc++.1.dylib), independent of the
version of the Darwin kernel.
This commit adds support to the LIT infrastructure for testing against
Apple platforms using -arch and -platform options.
If the host is not on OS X, or the compiler type is not clang or apple-clang, then this commit has NFC.
If the host is on OS X and --param=target_triple=... is specified, then a warning is emitted to use arch and platform instead. Besides the warning, there's NFC.
If the host is on OS X and *no* target-triple is specified, then use the new deployment target logic. This uses two new lit parameters, --param=arch=<arch> and --param=platform=<platform>. <platform> has the form <name>[<version>].
By default, arch is auto-detected from clang -dumpmachine, and platform is "macosx".
If the platform doesn't have a version:
For "macosx", the version is auto-detected from the host system using sw_vers. This may give a different version than the SDK, since new SDKs can be installed on older hosts.
Otherwise, the version is auto-detected from the SDK version using xcrun --show-sdk-path.
-arch <arch> -m<name>-version-min=<version> is added to the compiler flags.
The target triple is computed as <arch>-apple-<platform>. It is *not* passed to clang, but it is available for XFAIL and UNSUPPORTED (as is with_system_cxx_lib=<target>).
For convenience, apple-darwin and <arch>-apple-darwin are added to the set of available features.
There were a number of tests marked to XFAIL on x86_64-apple-darwin11
and x86_64-apple-darwin12. I updated these to
x86_64-apple-macosx10.7 and x86_64-apple-macosx10.8.
