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 change implements generation of a function which may be used by a backend to check if a given instruction is supported for a specific subtarget.

When nesting INSERT_SUBREG and EXTRACT_SUBREG, GlobalISelEmitter would
fail to find the register class of the nested node. This patch fixes
that for registers with subregs.

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.

Historically, we have told contributors that GnuWin32 is a pre-requisite
because our tests depend on utilities such as sed, grep, diff, and more.
However, Git on Windows includes versions of these utilities in its
installation. Furthermore, GnuWin32 has not been updated in many years.
For these reasons, it makes sense to have the ability to run llvm tests
in a way that is both:
a) Easier on the user (less stuff to install)
b) More up-to-date (The verions that ship with git are at least as
new, if not newer, than the versions in GnuWin32.
We add support for this here by attempting to detect where Git is
installed using the Windows registry, confirming the existence of
several common Unix tools, and then adding this location to lit's PATH
environment.

This patch adds support for the lxvp, lxvpx, plxvp, stxvp, stxvpx and pstxvp
instructions in the PowerPC backend. These instructions allow loading and
storing VSX register pairs. This patch also adds the VSRp register class
definition needed for these instructions.

Add the --include-generated-funcs option to update_cc_test_checks.py so that any
functions created by the compiler that don't exist in the source will also be
checked.
We need to maintain the output order of generated function checks so that
CHECK-LABEL works properly. To do so, maintain a list of functions output for
each prefix in the order they are output. Use this list to output checks for
generated functions in the proper order.

When generating matching tables for GlobalISel, TableGen would output
"::zero_reg" whenever encountering the zero_reg, which in turn would
result in compilation error. This patch fixes that by instead outputting
NoRegister (== 0), which is the same result that TableGen produces when
generating matching tables for ISelDAG.
