decided to use OS versions to select ABI, and no one is relying on the

Also use elfv2 on powerpc64-linux-musl.
Users can always use -mabi=elfv1 and -mabi=elfv2 to override the default

Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

HermitCore is a POSIX-compatible kernel for running a single application in an isolated environment to get maximum performance and predictable runtime behavior. It can either be used bare-metal on hardware or a VM (Unikernel) or side by side to an existing Linux system (Multikernel).
Due to the latter feature, HermitCore binaries are marked with ELFOSABI_STANDALONE to let the Linux ELF loader distinguish them from regular Unix/Linux binaries and load them using the HermitCore "proxy" tool.

LLVM triple normalization is handling "unknown" and empty components
differently; for example given "x86_64-unknown-linux-gnu" and
"x86_64-linux-gnu" which should be equivalent, triple normalization
returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's
config.sub returns "x86_64-unknown-linux-gnu" for both
"x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the
triple normalization to behave the same way, replacing empty triple
components with "unknown".

Initial patch adding assembly support for Armv8.4-A.
Besides adding v8.4 as a supported architecture to the usual places, this also
adds target features for the different crypto algorithms. Armv8.4-A introduced
new crypto algorithms, made them optional, and allows different combinations:
- none of the v8.4 crypto functions are supported, which is independent of the
implementation of the Armv8.0 SHA1 and SHA2 instructions.
- the v8.4 SHA512 and SHA3 support is implemented, in this case the Armv8.0
SHA1 and SHA2 instructions must also be implemented.
- the v8.4 SM3 and SM4 support is implemented, which is independent of the
implementation of the Armv8.0 SHA1 and SHA2 instructions.
- all of the v8.4 crypto functions are supported, in this case the Armv8.0 SHA1
and SHA2 instructions must also be implemented.
The v8.4 crypto instructions are added to AArch64 only, and not AArch32,
and are made optional extensions to Armv8.2-A.
The user-facing Clang options will map on these new target features, their
naming will be compatible with GCC and added in follow-up patches.

Until this patch, only `powerpc` and `ppc32` were recognized as valid
PowerPC 32-bit architectures in a target triple. This was incompatible
with the triple `ppc-apple-darwin` as returned for libObject. I found
out about this when working on a test case using a binary generated on
an old PowerBook G4.
We had the choice of either fix this in the Mach-O object parser or
in the Triple implementation. I chose the latter because it feels like
the most canonical place.

Apple's iOS, tvOS and watchOS simulator platforms have never been clearly
distinguished in the target triples. Even though they are intended to
behave similarly to the corresponding device platforms, they have separate
SDKs and are really separate platforms from the compiler's perspective.
Clang now defines a macro when building for one of these simulator platforms
(r297866) but that relies on the very indirect mechanism of checking to see
which option was used to specify the minimum deployment target. That is not
so great. Swift would also like to distinguish these simulator platforms in
a similar way, but unlike Clang, Swift does not use a separate option to
specify the minimum deployment target -- it uses a -target option to
specify the target triple directly, including the OS version number.
Using a different target triple for the simulator platforms is a much
more direct and obvious way to specify this. Putting the "simulator" in
the environment component of the triple means the OS values can stay the
same and existing code the looks at the OS field will not be affected.

Summary:
Using c++11 enum classes ensures that only valid enum values are used
for ArchKind, ProfileKind, VersionKind and ISAKind. This removes the
need for checks that the provided values map to a proper enum value,
allows us to get rid of AK_LAST and prevents comparing values from
different enums. It also removes a bunch of static_cast
from unsigned to enum values and vice versa, at the cost of introducing
static casts to access AArch64ARCHNames and ARMARCHNames by ArchKind.
FPUKind and ArchExtKind are the only remaining old-style enum in
TargetParser.h. I think it's beneficial to keep ArchExtKind as old-style
enum, but FPUKind can be converted too, but this patch is quite big, so
could do this in a follow-up patch. I could also split this patch up a
bit, if people would prefer that.
