This PR is part of a series to upstream managarm support, as laid out in
the
[RFC](https://discourse.llvm.org/t/rfc-new-proposed-managarm-support-for-llvm-and-clang-87845/85884/1).
This PR is a follow-up to #87845 and #138854.

This PR hides the reference-counted pointer that holds `TargetOptions`
from the public API of `CompilerInvocation`. This gives
`CompilerInvocation` an exclusive control over the lifetime of this
member, which will eventually be leveraged to implement a copy-on-write
behavior.
There are two clients that currently share ownership of that pointer:
* `TargetInfo` - This was refactored to hold a non-owning reference to
`TargetOptions`. The options object is typically owned by the
`CompilerInvocation` or by the new `CompilerInstance::AuxTargetOpts` for
the auxiliary target. This needed a bit of care in `ASTUnit::Parse()` to
keep the `CompilerInvocation` alive.
* `clangd::PreambleData` - This was refactored to exclusively own the
`TargetOptions` that get moved out of the `CompilerInvocation`.

from arm-apple-none-macho (#122427)
arm-apple-none-macho uses DarwinTargetInfo which provides several Apple
specific macros. arm64-apple-none-macho however just uses the generic
AArch64leTargetInfo and doesn't get any of those macros. It's not clear
if everything from DarwinTargetInfo is desirable for
arm64-apple-none-macho, so make an AppleMachOTargetInfo to hold the
generic Apple macros and a few other basic things.

This is a revert of ef5e7f90ea4d5063ce68b952c5de473e610afc02 which was a
temporary partial revert of 77ac823fd285973cfb3517932c09d82e6a32f46d.
The le32 and le64 targets are no longer necessary to retain, so this

This change seeks to add support for vendor flavoured SPIRV - more
specifically, AMDGCN flavoured SPIRV. The aim is to generate SPIRV that
carries some extra bits of information that are only usable by AMDGCN
targets, forfeiting absolute genericity to obtain greater expressiveness
for target features:
- AMDGCN inline ASM is allowed/supported, under the assumption that the
[SPV_INTEL_inline_assembly](https://github.com/intel/llvm/blob/sycl/sycl/doc/design/spirv-extensions/SPV_INTEL_inline_assembly.asciidoc)
extension is enabled/used
- AMDGCN target specific builtins are allowed/supported, under the
assumption that e.g. the `--spirv-allow-unknown-intrinsics` option is
enabled when using the downstream translator
- the featureset matches the union of AMDGCN targets' features
- the datalayout string is overspecified to affix both the program
address space and the alloca address space, the latter under the
assumption that the
[SPV_INTEL_function_pointers](https://github.com/intel/llvm/blob/sycl/sycl/doc/design/spirv-extensions/SPV_INTEL_function_pointers.asciidoc)
extension is enabled/used, case in which the extant SPIRV datalayout
string would lead to pointers to function pointing to the private
address space, which would be wrong.
Existing AMDGCN tests are extended to cover this new target. It is
currently dormant / will require some additional changes, but I thought
I'd rather put it up for review to get feedback as early as possible. I
will note that an alternative option is to place this under AMDGPU, but
that seems slightly less natural, since this is still SPIRV, albeit
relaxed in terms of preconditions & constrained in terms of
postconditions, and only guaranteed to be usable on AMDGCN targets (it
is still possible to obtain pristine portable SPIRV through usage of the
flavoured target, though).

(#91407)
This change set restores commit 080978dd2067d0c9ea7e229aa7696c2480d89ef1 that was reverted to address ASAN
failures and includes a fix for the ASAN failures.
Following is the description of the change:
An earlier commit provided a way to decouple DXIL version from Shader
Model version by representing the DXIL version as `SubArch` in the DXIL
Target Triple and adding corresponding valid DXIL Arch types.
This change constructs DXIL target triple with DXIL version that is
deduced from Shader Model version specified in the following scenarios:
1. When compilation target profile is specified:
For e.g., DXIL target triple `dxilv1.8-unknown-shader6.8-library` is
constructed when `-T lib_6_8` is specified.
2. When DXIL target triple without DXIL version is specified:
For e.g., DXIL target triple `dxilv1.8-pc-shadermodel6.8-library` is
constructed when `-mtriple=dxil-pc-shadermodel6.8-library` is specified.
Updated relevant HLSL tests that check for target triple.

Issue: https://github.com/ClangBuiltLinux/linux/issues/1997

This adds support for the AArch64 soft-float ABI. The specification for
this ABI was added by https://github.com/ARM-software/abi-aa/pull/232.
Because all existing AArch64 hardware has floating-point hardware, we
expect this to be a niche option, only used for embedded systems on
R-profile systems. We are going to document that SysV-like systems
should only ever use the base (hard-float) PCS variant:
https://github.com/ARM-software/abi-aa/pull/233. For that reason, I've
not added an option to select the ABI independently of the FPU hardware,
instead the new ABI is enabled iff the target architecture does not have
an FPU.
For testing, I have run this through an ABI fuzzer, but since this is
the first implementation it can only test for internal consistency
(callers and callees agree on the PCS), not for conformance to the ABI
spec.

This adds Hurd toolchain support to Clang's driver in addition to

- FreeBSD removed big-endian arm with 12.0.
- OpenBSD never had big-endian arm support. I added it just in case, but it has
never been used.
- Remove sparcel bits. It was sprinkled in a few places but it will never be a
thing.
- Remove 32-bit sparc bits for FreeBSD. FreeBSD has never had 32-bit sparc
support.
- Remove sparc64 IAS test as support was enabled across the board awhile ago.

Minix is a ToolChain that was added back in 2010 but has been
unmaintained with no test. The constructed command line contains
/usr/gnu/include/c++/4.4.3 and CompilerRT-Generic which are unlikely
working for a long time.
Contiki is a barebone ToolChain that just enables safestack.
This doesn't justify a new ToolChain.
Remove these ToolChains so that their target triples will use Generic_ELF instead.
If these developers feel like having an updated llvm-project is useful,
fixing other build issues and adding a new ToolChain is much better than
having the unmaintained ToolChains.

Currently the diag is emitted even when there is no
target feature specified on command line for OpenMP.
This is because the function to initialize feature map
is also used with cached feature string. The fix is to
only diag when the feature map is initialized with
feature strings from command line options.

POWER Darwin support in the backend has been removed for some time: https://discourse.llvm.org/t/rfc-remove-darwin-support-from-power-backends
but Clang still has the TargetInfo and other remnants lying around.
This patch does some cleanup and removes those and other related frontend support still remaining. We adjust any tests using the triple to either remove
the test if unneeded or switch to another Power triple.

With the initial support added, clang can compile `helloworld` C
to executable file for loongarch64. For example:
```
$ cat hello.c
int main() {
printf("Hello, world!\n");
return 0;
}
$ clang --target=loongarch64-unknown-linux-gnu --gcc-toolchain=xxx --sysroot=xxx hello.c
```
The output a.out can run within qemu or native machine. For example:
```
$ file ./a.out
./a.out: ELF 64-bit LSB pie executable, LoongArch, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-loongarch-lp64d.so.1, for GNU/Linux 5.19.0, with debug_info, not stripped
$ ./a.out

build version load commands
This patch extends clang frontend to add metadata that can be used to emit macho files with two build version load commands.
It utilizes "darwin.target_variant.triple" and "darwin.target_variant.SDK Version" metadata names for that.
MachO uses two build version load commands to represent an object file / binary that is targeting both the macOS target,
and the Mac Catalyst target. At runtime, a dynamic library that supports both targets can be loaded from either a native
macOS or a Mac Catalyst app on a macOS system. We want to add support to this to upstream to LLVM to be able to build
compiler-rt for both targets, to finish the complete support for the Mac Catalyst platform, which is right now targetable
by upstream clang, but the compiler-rt bits aren't supported because of the lack of this multiple build version support.
