[clang-tidy] Fix false positives about reinitialization detection in `bugprone-use-after-move` (#197438)
When calling base class's `operator=` through derived object, a implicit
cast with `UncheckedDerivedToBase` will be generated:
```
void foo() {
Base b;
Derived d;
std::move(d);
d = b;
}
```
AST for `d = b`'s `d`:
```
|-ImplicitCastExpr <col:3> 'GH62206::Base' lvalue <UncheckedDerivedToBase (Base)>
| `-DeclRefExpr <col:3> 'Derived' lvalue Var 0x1d11a400 'd' 'Derived'
```
This patch considers possible `implicitCastExpr` in the reinit matcher,

[PHIElimination] Clear stale LiveVariables AliveBlocks for undef PHI sources (#197764)
When PHI Elimination lowers a PHI with an undef source (e.g. from an
`IMPLICIT_DEF),` it skips the LiveVariables kill/AliveBlocks update
because the value is undefined. However, the source register's
AliveBlocks may still mark intermediate blocks as live-through from its
definition to the (now eliminated) PHI use. This causes MachineVerifier
failures in EXPENSIVE_CHECKS builds.
Fix by calling `recomputeForSingleDefVirtReg` on undef source registers
when their last PHI use on a CFG edge is eliminated, which correctly
clears the stale AliveBlocks entries.
Fixes the EXPENSIVE_CHECKS failure introduced by #196895.
ap24-auth-gssapi: Import apache2.4 module mod_auth_gssapi-1.6.5
This is a modern replacement for mod_auth_kerb (www/ap-auth-kerb),
built with the standardized GSSAPI rather than with the not-quite-so
standardized libkrb5.
[OpenACC] Fix invalid using inside of an openacc directive (#198058)
Bug report #197858 comes up with a reproducer where an invalid `using`
declaration checks the Scope it is in, and asserts if it isn't in a
DeclScope. Since all of the important directives that create scopes end
up causing a new scope anyway, this patch adds 'DeclScope' to the parse
scope for an OpenACC directive. This follows the guidance of the OpenMP
directives.
Fixes: #197858
[clang][bytecode] Fix wrong 'never produces a constant expression' diagnostic with static data members (#197881)
They can be initialized later, similar to extern variables.
thunderbolt: make code -Wunused clean
This change modifies code paths and uses `__diagused` to address `-Wunused`
issues that occur when `THUNDERBOLT_DEBUG` == `0`.

Downgrade mismatch when checking pack version minor from error to
warning.
With relative API stability in Godot 3.x, don't error when Godot bin
minor is less than pack file minor, warn instead. This is stop refusing
to run games that are built with HEAD and report higher minor version
than latest release.

[libc] Make cpp::byte alias-safe (#194171)
Change LIBC_NAMESPACE::cpp::byte from an enum-backed type to unsigned
char so libc’s raw-memory utilities and sorting code can legally access
object representations without violating C++ strict-aliasing rules.
[MemoryBuiltins] Capture more information for alloc/free from attributes
We now read the `alloc_align` attribute to provide better alignment
information to users. `alloc-family` should be used as well, as
described in the LangRef. Two new helpers provide argument numbers,
rather than values.
[flang] Recognize effects on non-addressable resources in opt-bufferization.
opt-bufferization has been only handling `fir::DebuggingResource`
explicitly. This patch adds support for other non-addressable
resources, such as `fir::VolatileMemoryResource`. This allows
merging elemental/assign for the `volatile_src_nonvolatile_dst`
example in the updated LIT test.
[flang] Pass-through fir.volatile_cast in FIR AliasAnalysis.
It should be safe to pass-through `fir.volatile_cast` for the purpose
of alias analysis. The missing pass-through prevented optimization
of the `nonvolatile_src_volatile_dst` test (see updated LIT test).
[libc] Fix install-libc to work with LLVM_LIBC_FULL_BUILD=OFF (#197366)
Initialize variables that are conditionally set to avoid undefined
references in install-libc and install-libc-stripped targets:
- Initialize added_bitcode_targets to empty string (may be undefined
when LIBC_TARGET_OS_IS_GPU=OFF)
- Initialize startup_target to empty string and only set to
"libc-startup" when both LLVM_LIBC_FULL_BUILD=ON and NOT baremetal
(startup directory is only included in full builds)
- Initialize header_install_target to empty string (may be undefined
when LLVM_LIBC_FULL_BUILD=OFF)
[DirectX] Do not emit !dbg on function definitions (#197449)
This was not done in LLVM 3.7. Instead, the !DISubprogram contains a
reference to the function (already emitted).
