x11/xconfig: Update to 3.6
Remove unused packages before setting up drivers, so an early exit
during NVIDIA setup no longer leaves VM guest packages installed.
[X86][AsmParser] Fix Intel mask position for AVX512PF prefetch instructions (#233869)
AVX512PF gather/scatter prefetch instructions reject a memory operand
followed by a mask decorator in Intel syntax. LLVM also prints the mask
as a leading operand, producing Intel disassembly that cannot be
reassembled.
Move the mask after the memory operand in the Intel assembly variant of
`avx512_gather_scatter_prefetch`. Preserve the AT&T variant and the
outer dialect selection so the literal mask braces survive TableGen
processing.
Add Intel MC tests for all 16 mnemonics, using the 32 existing AT&T
encoding expectations. Cover sized/unsized memory, high VSIB registers,
YMM/ZMM indices, k1-k7, scaled addressing, compressed displacement, and
assembly output round trips. Add diagnostics for missing/zero masks,
zeroing, incorrect VSIB widths, and incorrect memory size.
Update the existing APX disassembler expectation to the corrected mask

[VPlan] CSE replicated loads (#234525)
This improves a pattern found in 736.ocio_r, see
https://github.com/llvm/llvm-project/pull/195886#issuecomment-6196462669
In the following loop `s` isn't noalias, so a runtime alias check needs
to be added:
```c
void f(const float *s, const unsigned short *in, float *out, long n) {
for (long i = 0; i < n; i++) {
out[4 * i + 0] = in[4 * i + 0] * *s;
out[4 * i + 1] = in[4 * i + 1] * *s;
out[4 * i + 2] = in[4 * i + 2] * *s;
out[4 * i + 3] = in[4 * i + 3] * *s;
}
}

Remove unused packages before setting up drivers
Package removal was queued and only run after main returned, so any
early exit during driver setup (e.g. NVIDIA) skipped it and left
packages like virtualbox-ose-additions installed. The remove_*
functions now delete right away, before the setup functions run.
Also drop the leftover remove_qemu calls, which aborted the script
under set -e, and stop generating xorg.conf with X -configure for
NVIDIA.
www/py-flask-assets: Update to 2.1.0
2.0 uses flask._request_ctx_stack, which Flask 3 removed, so
flask_assets fails to import with the Flask in the tree. 2.1.0 works
with Flask 3.
While here, add concurrent to USE_PYTHON.
Switch to USE_PYTHON=pep517 (the package metadata becomes dist-info).
Take maintainership, as offered by kevans@.

[lldb] Report why a script interpreter is unavailable (#235947)
When Python can't be loaded, no plugin registers for it and LLDB falls
back to ScriptInterpreterNone, which claims LLDB was built without
scripting support. The real error was dropped during initialization.
Record the error per language in the PluginManager where the failure
happens, and pass the requested language to the create callback so
ScriptInterpreterNone can report it from the relevant commands.
For a language LLDB was built with but has no recorded error, report
that its plugin wasn't loaded.

powerpc: Avoid deadlock when CPUs exchange threads
The PowerPC context switch waited for the incoming thread to leave
blocked_lock before releasing the outgoing thread. If two CPUs selected
each other's running threads concurrently, both CPUs waited for the
other to perform the release and neither could progress. This appeared
as intermittent boot hangs under QEMU MTTCG when taskqueue threads were
bound to opposite CPUs.
8df2e5421468 ("powerpc: put the isync inside the TD_LOCK()...")
attempted to fix the same hang by moving isync into the polling loop.
That did not address the circular wait: isync cannot cause either CPU to
execute the release store after the loop. It only added context
synchronization to failed iterations and changed timing. Move isync back
to the successful exit, which preserves acquire ordering for subsequent
context loads.
Match the ordering used by other architectures: publish the outgoing
thread's new lock before waiting for the incoming thread. Apply the

[DebugInfo] Preserve original value when replacing instructions (#234978)
There are several places in `correlated-propagation` where an
instruction is replaced without salvaging the debug info. The value
computed by the new instruction may be different to the original that
was replaced. This leads to debuggers like lldb reporting incorrect
values for variables (reporting the value of the new instruction).
This PR makes sure the compiler salvages the debug information of the
replaced instructions before replacing them.

[compiler-rt][Android] Filter out linker warnings from stderr in android_run.py (#235973)
Older Android dynamic linkers (e.g. API 24) print `WARNING: linker: ...`
lines to stderr for newer ELF flags/tags such as `DT_FLAGS_1=0x8000001`
(`DF_1_PIE`) and `DT_AARCH64_BTI_PLT` (`0x70000001`). When these lines
are emitted at startup or when spawning `llvm-symbolizer`, they break
tests using `count 0`, `CHECK-NEXT`, or `CHECK-NOT` on

www/mod_wsgi4: a port for mod_wsgi 4.9.4 for python 2.7
This brings back mod_wsgi 4.9.4 which is the last supported
version for python 2.7.
This is specifically for clusteradm infrastructure and not
as a port for normal users.
Note this currently clashes with www/mod_wsgi as it also
builds and installs the module as "mod_wsgi.so".
