  [libc] Add llvm-libc-types header deps for <complex.h>. (#164422)

complex.yaml declares types cfloat16, cfloat128 and float128 in its
'types' section, causing the output complex.h to #include three headers
with names of the form "llvm-libc-types/cfloat16.h". But
include/CMakeLists.txt doesn't mention those types as dependencies in
the `add_header_macro` call for complex.h. As a result, cfloat16.h and
cfloat128.h are not installed by the 'install' target, but complex.h
still tries to to include them.

The third type header, float128.h, doesn't have this problem because the
`add_header_macro` math.h does mention it as a dependency. So I've added
all three headers as dependencies in complex.h, following the same
pattern, and now the install target installs the missing two headers.

  [clang] callee_type metadata for indirect calls (#163233)

Create and add generalized type identifier metadata to indirect calls,
and to functions which are potential indirect call targets.

The functions carry the !type metadata. The indirect callsites carry a
list of !type metadata values under !callee_type metadata.

  [NFC][Clang][Diagnostics] Remove the DeferHint parameter of Diags(...) in favour of DeferHintRAII (#161517)

The `DeferHint` was misused at several callsites, where a `Decl*` was
implicitly casted to `bool`.

This patch proposes removing the `DeferHint` parameter and relying on
`DeferDiagsRAII` to set if Clang should defer the diagnostics.

  [libc] implement `inet_aton` (#162651)

This patch adds the implementation for `inet_aton` function. Since this
function is not explicitly included in POSIX, I have marked it with
`llvm_libc_ext`. It is widely available and commonly used, and can also
be used to implement `inet_addr`, which is included in POSIX.

  [SPIR-V] Use `OpImageFetch` instead of `OpImageRead` when loading from read-only `Buffer` resource. (#163626)

Currently, the spir-v validator fails if `OpImageRead` instruction is
used when loading from read-only `Buffer`.
### Unit Test
```hlsl
RWBuffer<uint> rwbuff;
Buffer<uint>  buff;

[numthreads(1,1,1)]
void main() {
    rwbuff[99] = buff[98];
    rwbuff[97] = rwbuff[96];
}
```
This also unblocks adding a test case that adds a special capability
when using a non-uniform index on `Buffer` arrays.

`<binop>` could be `add`, `sub`, `max`, `min`, `and`, `or`, `xor`, and
`nand`.

  [acc][flang] lowering of acc declare on COMMON variables (#163676)

COMMON variables are treated as locals and lowered to structured
declares currently. This is incorrect because variables that are COMMON
should be treated as globals. Added implementation to treat these
variables differently.

  [compiler-rt] [CMake] Skip find_darwin_sdk_dir on disabled platforms (#163591)

find_darwin_sdk_dir can be slow, especially if xcrun does not
immediately find the corresponding SDK (i.e. because it is missing).

This skips those checks if the user has already set the corresponding
CMake variable to disable the platform anyway.

  [CIR] Implement inline builtin functions (#163911)

This patch implements the handling of inline builtin functions in CIR.
There is a known limitation in CIR where direct calls to shadowed inline
builtin functions are generated instead of the intrinsic. This is
expected to be fixed by the introduction of the nobuiltin attribute in a
future patch.

  [RISCV][LLVM] Enable atomics for 'Zalrsc' (#163672)

The 'A' atomics extension is composed of two subextensions, 'Zaamo'
which has atomic memory operation instructions, and 'Zalrsc' which has
load-reserve / store-conditional instructions.

For machines where 'Zalrsc' is present, but 'Zaamo' is not, implement
and enable atomics memory operations through pseudo expansion. Updates the
predication and lowering control to be more precise about which 'Zaamo'/'Zalrsc'
feature was truly requisite.

There will be no functional change to subtargets supporting 'A', while
allowing 'Zalrsc' only subtargets to utilize atomics at an increased code
footprint.

  [AllocToken] Introduce llvm.alloc.token.id intrinsic (#163632)

Introduce a new intrinsic, `llvm.alloc.token.id`, to allow compile-time
querying of allocation token IDs.

The `AllocToken` pass is taught to recognize and lower this intrinsic.
It extracts the `!alloc_token` metadata from the intrinsic's argument,
feeds it into the same token-generation logic used for instrumenting allocation
calls, and replaces the intrinsic with the resulting constant integer token ID.

This is a prerequisite for `__builtin_infer_alloc_token`. The pass now
runs on all functions to ensure intrinsics are lowered, but continues to
only instrument allocation calls in functions with the
`sanitize_alloc_token` attribute.
