[LoopIdiom] Select llvm.experimental.memset.pattern intrinsic rather than memset_pattern16 libcall (#126736)
In order to keep the change as incremental as possible, this only
introduces the memset.pattern intrinsic in cases where memset_pattern16
would have been used. Future patches can enable it on targets that don't
have the intrinsic, and select it in cases where the libcall isn't
directly usable. As the memset.pattern intrinsic takes the number of
times to store the pattern as an argument unlike memset_pattern16 which
takes the number of bytes to write, we no longer try to form an i128
pattern.
Special care is taken for cases where multiple stores in the same loop
iteration were combined to form a single pattern. For such cases, we
inherit the limitation that loops such as the following are supported:
```
for (unsigned i = 0; i < 2 * n; i += 2) {
f[i] = 2;
f[i+1] = 2;
}
```
But the following doesn't result in a memset.pattern (even though it
could be, by forming an appropriate pattern):
```
for (unsigned i = 0; i < 2 * n; i += 2) {
f[i] = 2;
f[i+1] = 3;
}
```
Addressing this existing deficiency is left for a follow-up due to a
desire not to change too much at once (i.e. to target equivalence to the
current codegen).
A command line option is introduced to force the selection of the
intrinsic even in cases it wouldn't be (i.e. in cases where the libcall
wouldn't have been selected). This is intended as a transitionary option
for testing and experimentation, to be removed at a later point.
The only platforms this should impact are those that have the memset_pattern16 libcall (Apple platforms). Testing performed to check for no unexpected codegen changes is described here https://github.com/llvm/llvm-project/pull/126736#issuecomment-3005097468

[SPIRV] Add more id and range builtIns (#143909)
The patch adds intrinsics and lowering logic for GlobalSize,
GlobalOffset, SubgroupMaxSize, NumWorkgroups, WorkgroupSize,
WorkgroupId, LocalInvocationId, GlobalInvocationId, SubgroupSize,
NumSubgroups, SubgroupId and SubgroupLocalInvocationId SPIR-V builtins.
The patch also extend spv_thread_id, spv_group_id and
spv_thread_id_in_group to return anyint rather than i32. This allows the
intrinsics to support the opencl environment.
For each of the intrinsics, new clang builtins were added as well as a
binding for the SPIR-V "friendly" format. The original format doesn't
define such binding (uses global variables) but it is not possible to
express the Input SC which is normally required by the environement
specs, and using builtin functions is the most usual approach for other
backend and programming models.

[clang][AST] Fix positioning of preserve cconv attributes in TypePrinter (#147285)
TypePrinter currently generates function pointer types that do not
compile when using the `preserve_.*` calling conventions as per
https://clang.llvm.org/docs/AttributeReference.html#preserve-all ff.
Running clang with `-Xclang -ast-print` on the following:
```cc
using IN1 = void (__attribute__((preserve_most)) *)();
using IN2 = __attribute__((preserve_most)) void (*) ();
```
outputs:
```cc
using IN1 = void (*)() __attribute__((preserve_most));
using IN2 = void ((*))() __attribute__((preserve_most));
```
However, this does not compile:
```cc
<source>:3:23: error: expected ';' after alias declaration
3 | using IN1 = void (*)() __attribute__((preserve_most));
```
This PR updates TypePrinter such that output is correct and compiles:
```cc
using IN1 = __attribute__((preserve_most)) void (*)();
using IN2 = __attribute__((preserve_most)) void ((*))();
```
I've verified via `-ast-dump` that the AST looks equivalent.

[Clang] Respect MS layout attributes during CUDA/HIP device compilation (#146620)
This patch fixes an issue where Microsoft-specific layout attributes,
such as __declspec(empty_bases), were ignored during CUDA/HIP device
compilation on a Windows host. This caused a critical memory layout
mismatch between host and device objects, breaking libraries that rely
on these attributes for ABI compatibility.
The fix introduces a centralized hasMicrosoftRecordLayout() check within
the TargetInfo class. This check is aware of the auxiliary (host) target
and is set during TargetInfo::adjust if the host uses a Microsoft ABI.
The empty_bases, layout_version, and msvc::no_unique_address attributes
now use this centralized flag, ensuring device code respects them and
maintains layout consistency with the host.

Fix test failure introduced in ab187bb
This patch, #147285 introduced a test that used
preserve_none/preserve_all/preserve_most for the purposes of validating
its ast-dump. However, this attribute isn't supported on some
platforms, so this patch adds a triple to the test to ensure we try to
run it as a non-supported platform.
As this is simply an ast-dump test, there is no value to running it on
other configurations.

[lldb][test] Merge MSVC STL std::(u8)string tests into generic directory (#147525)
Now that most STL formatter tests have been moved to `generic`. Do the
same for the MSVC tests (which are currently just for `std::string`).
The `std::string` test was mostly the same (MSVC just had 1 additional
check, which I moved over).
We also only tested `u8string` with MSVC. So i moved those into
`generic` as-is. I kept it separate from the existing std::string tests
since it requires c++20.
The tests are currently failing for libc++ and libstdc++ because MSVC
had a test case which checked that:
```
std::string overwritten_zero("abc");
const_cast<char *>(overwritten_zero.data())[3] = 'd';
```
prints as `"abc"`. But libc++ and libstdc++ print it as `"abcd"` (which
seems like the more correct thing to do?)

[flang] Avoid undefined behaviour when parsing format expressions (#147539)
The test flang/test/Semantics/io08.f90 was failing when UBSAN was
enabled:
```
/home/david.spickett/llvm-project/flang/include/flang/Common/format.h:224:26: runtime error: signed integer overflow: 10 * 987654321098765432 cannot be represented in type 'int64_t' (aka 'long')
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /home/david.spickett/llvm-project/flang/include/flang/Common/format.h:224:26
```
This is because the code was effectively:
* Take the risk of UB happening
* Check whether it happened or not
Which UBSAN is obviously not going to like. Instead of checking after
the fact, use llvm's helpers that catch overflow without actually doing
it.

[analyzer] Remove redundant bug type DoubleDelete (#147542)
This commit removes the DoubleDelete bug type from `MallocChecker.cpp`
because it's completely redundant with the `DoubleFree` bug (which is
already used for all allocator families, including new/delete).
This simplifies the code of the checker and prevents the potential
confusion caused by two semantically equivalent and very similar, but
not identical bug report messages.

[AArch64][GISel] Handle small vector fadd reductions.
This adds some test cases for v2 and v3 half vector fadd reductions. In doing
so it appears that GlobalISel was having trouble lowering the smaller vector
sizes. Add some basic handling by widening to a power2 or scalarizing if
necessary. Larger vectors are still having problems as FewerElements currently
requires the number of elements to be modula the vector length.

[clang][diagnostics] Refactor "warn_doc_api_container_decl_mismatch" to use enum_select (#146433)
Related: https://github.com/llvm/llvm-project/issues/123121
This patch refactors the `warn_doc_api_container_decl_mismatch`
diagnostic to use enum_select instead of select. This gets rid of magic
numbers and improves readability in the caller site.
