I recently had to run the test suite with a debug Python which got started
warning about some invalid escape sequences in LLDB's Python code. They all
attempt to add a backslash by doing a single backslash instead of a double
backslash in a normal string. This seems to work fine for now, but Python says
this behaviour is deprecated, so this patch turns all those strings into raw
strings (where a single backslash is actually a single backslash)

Commit 6e56046f65 may trigger SEGV in llvm-tablegen if the latter
is built with -DLLVM_OPTIMIZED_TABLEGEN=OFF. The reason of SEGV was
accessing stale memory after expansion of std::vector.
It's built with just-built clang, like all other compiler-rt parts
in the GN build.
This requires adding some cross build support to the mac toolchain.
Also add explicit mmacosx-version-min and miphoneos-version-min
flags to the build.
ios.a is only built with the arm64 slice, iossim.a only with the
x86_64 slice for now. (The latter should maybe become host_cpu
when Arm Macs become a common iOS development platform.)
With this, it's possible to build chromium/iOS with a GN-built LLVM.

Summary: Since willreturn will soon be added as default attribute, we can end up with both noreturn and willreturn on the same intrinsic. This was exposed by llvm.wasm.throw which has IntrNoReturn.

The tests previously relied on the `short.py` and `FirstTest.subTestA`
script being executed on a machine within a short time window (1 or 2
seconds). While this "seems to work" it can fail on resource constrained
machines. We could bump the timeout a little bit (bumping it too
much would mean the test would take a long time to execute) but it wouldn't
really solve the problem of the test being prone to failures.
This patch tries to remove this flakeyness by separating testing into
two separate parts:
1. Testing if a test can hit a timeout.
2. Testing if a test can run to completion in the presence of a
timeout.
This way we can give (1.) a really short timeout (to make the test run
as fast as possible) and (2.) a really long timeout. This means for (2.)
we are no longer trying to rely on the "short" test executing within
some short time window. Instead the window is now 3600 seconds which
should be long enough even for a heavily resource constrained machine to
execute the "short" test.
Thanks to Julian Lettner for suggesting this approach. This superseeds
my original approach in https://reviews.llvm.org/D88807.
This patch also changes the command line override test to run the quick
test rather than the slow one to make the test run faster.

This is a cherrypick of the upstream fix commit ffe1342 onto
`llvm/utils/benchmark` and `libcxx/utils/google-benchmark`.
This adds CycleTimer implementation for M680x0, which simply
uses `gettimeofday` same as MIPS.

Summary:
This patch adds an error to Clang that detects if OpenMP offloading is
used between two architectures with incompatible pointer sizes. This
ensures that the data mapping can be done correctly and solves an issue
in code generation generating the wrong size pointer. This patch adds a
new lit substitution, %omp_powerpc_triple that, if the system is 32-bit or
64-bit, sets the powerpc triple accordingly. This was required to fix
some OpenMP tests that automatically populated the target architecture.

This should fix the test failures on the clang win64 bot:
http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/18830
It has been red since Sept 23-ish.
This was subtle to debug. Windows has 'find' and 'sort' utilities in
C:\Windows\system32, but they don't support all the same flags as the
coreutils programs. I configured the buildbot above with Python 2.7
64-bit (hey, it was set up in 2016). When I installed git for Windows, I
opted to add all the Unix utilities that come with git to the system
PATH. This is *almost* enough to make the LLVM tests pass, but not
quite, because if you use the system PATH, the Windows version of find
and sort come first, but the tests that use diff, cmp, etc, will all
pass. So only a handful of tests will fail, and with cryptic error
messages.
The code changed in this CL doesn't work with Python 2. Before
Python 3.2, the winreg.OpenKey function did not accept the `access=`
keyword argument, the caller was required to pass an unused `reserved`
positional argument of 0. The try/except/pass around the OpenKey
operation masked this usage error in Python 2.
Further, the result of the registry operation has to be converted from
unicode to add it to the environment, but that was incidental.
Key Locker provides a mechanism to encrypt and decrypt data with an AES key without having access
to the raw key value by converting AES keys into “handles”. These handles can be used to perform the
same encryption and decryption operations as the original AES keys, but they only work on the current
system and only until they are revoked. If software revokes Key Locker handles (e.g., on a reboot),
then any previous handles can no longer be used.
