[mlir][SparseTensor] Fix crash demapping alloc_tensor with a copy operand (#219319)

`TensorAllocDemapper` reconstructs demapped level sizes for a
`bufferization.alloc_tensor`/`tensor.empty` by pairing each dynamic
result
dimension with an entry from the op's `dynamic_sizes` operand list,
popping via
`ValueRange::front()`.

When an `alloc_tensor` has a `copy` operand instead of explicit dynamic
sizes,
`dynamic_sizes` is legitimately empty — the op's own verifier requires
that the
sizes are implied by the copy operand and must not be specified — so
`front()`
was called on an empty range and asserted:

```
llvm/include/llvm/ADT/STLExtras.h:1253: Assertion `!empty() && "expected non-empty range"' failed.

[clang-tools-extra] Add separate CLANG_TOOLS_EXTRA_INCLUDE_TESTS option (#215761)

clang-tools-extra tests depend on the llvm-bcanalyzer CMake target,
which exists in LLVM's CMake project but is not visible when Clang is
built separately from LLVM. This causes CMake errors when
CLANG_INCLUDE_TESTS is ON but the LLVM tools are not available.

This patch introduces CLANG_TOOLS_EXTRA_INCLUDE_TESTS as a separate
CMake option to control clang-tools-extra tests independently, allowing
users to build Clang with tests enabled (CLANG_INCLUDE_TESTS=ON) while
disabling clang-tools-extra tests (CLANG_TOOLS_EXTRA_INCLUDE_TESTS=OFF)
when building Clang separately from LLVM.

For backwards compatibility, CLANG_INCLUDE_TESTS=OFF continues
to turn off clang-tools-extra tests as well.

[analyzer] Fix handling of zero-sized elements in ArrayBound (#218712)

Previously the `security.ArrayBound` checker mishandled the following C
code under non-windows platforms where `sizeof(struct Empty) == 0`:
```c
struct Empty {};
struct Empty Array[10];
struct Empty foo(void) { return Array[5]; }
```
Here the checker produced a false positive with explanation "Access of
'Array' at byte offset 0, while it holds only 0 byte" -- that is, the
checker said that this accesses the past-the-end pointer, which is
usually invalid.

This commit suppresses this false positive by saying that accessing a
zero-sized object starting at the past-the-end pointer is valid.

This is implemented by adding an `AlsoAcceptEquality` flag for
`checkBounds`. This flag will also be useful for implementing checkers

[lld][WebAssembly] Do not coalesce segments with differing flags in -r (#219606)

In PR #210747 (commit 162d9f09299d), `addInputSegment` was changed to
union segment linking flags (`linkingFlags |= inSeg->flags`) so that
flags like `RETAIN` and `STRINGS` are preserved in `--relocatable`
output.

However, coalescing segments with differing linking flags by name alone
forces one chunk's semantics onto another:
- Clang emits ordinary string literals (`STRINGS`) and string literals
  containing embedded null characters (non-`STRINGS`) into sections
  named `.rodata..L.str`. When coalesced, non-mergeable segments
  received the `STRINGS` flag, causing downstream links to split and
  corrupt them.
- Similarly, coalescing a chunk with `RETAIN` and a chunk without
  `RETAIN` forces the un-retained chunk to inherit `RETAIN`, preventing
  `--gc-sections` from discarding it if it is unused.

Fix this by distinguishing segments by their linking flags in

[clang][Parse] Stop parsing declarator chunks after a parenthesized structured binding (#219270)

Fixes #218144
Fixes #193687

`ParseDirectDeclarator` stops right after a structured binding like `[a,
b]`, since nothing can follow it — but that check only covers the
unparenthesized form. For `([a, b])`, the binding gets parsed inside
`ParseParenDeclarator`, and the outer `ParseDirectDeclarator` doesn't
notice — it carries on into its suffix loop and parses a trailing `()`
as a function declarator. `([a, b])() {}` then looks like a function
definition, so `ActOnStartOfFunctionDef` gets handed a
`DecompositionDecl` where it expects a `FunctionDecl`:
`cast<FunctionDecl>` asserts, or segfaults later without assertions —
that's #193687. (The `b;` in the report is noise; `([a])() {}` alone
crashes.)

This patch makes `ParseDirectDeclarator` stop as well when the
parenthesized declarator turns out to be a structured binding, so

[libc] Disable float16 on 32-bit x86 without SSE2 (#219675)

Fixes #219668

Building llvm 23.1.0 (and current main) for 32-bit x86 without SSE2
fails since APFloat.cpp started including libc's shared/math.h. All the
errors come from the float16 headers:

```
libc/src/__support/FPUtil/BasicOperations.h:63:67: error: SSE register return with SSE2 disabled
libc/src/__support/math/acosf16.h:73:14: error: invalid conversion from type '_Float16' without option '-msse2'
```

The float16 detection in float16-macros.h checks __FLT16_MANT_DIG__.
Since GCC 14 that macro is defined on ia32 even without SSE2, where
_Float16 is storage-only and any arithmetic or returning by value is an
error.
The GCC 14 release notes say to check __SSE2__ for arithmetic support
instead: https://gcc.gnu.org/gcc-14/changes.html
