PREFIX_ADJOUT_FLAG_DEAD is no longer needed and can be replaced with
a check that the attrs pointer is NULL. Refactor the code now a bit
since the logic got a bit simpler.

science/colt: pin to openjdk8
It fails on jdk21:
error: as of release 9, '_' is a keyword, and may not be used as an identifier
Build.xml also needed an encoding="ISO-8859-1" in the javac target.
NB: Upstream didn't make a release since 2004.

[lldb] Add WebAssembly platform (#171507)
This PR adds a platform for WebAssembly. Heavily inspired by Pavel's
QemuUser, the platform lets you configure a WebAssembly runtime to run a
Wasm binary.
For example, the following configuration can be used to launch binaries
under the WebAssembly Micro Runtime (WARM):
```
settings set -- platform.plugin.wasm.runtime-args --heap-size=1048576
settings set -- platform.plugin.wasm.port-arg -g=127.0.0.1:
settings set -- platform.plugin.wasm.runtime-path /path/to/iwasm-2.4.0
```
With the settings above, you can now launch a binary directly under
WAMR:

cam: Reduce overly long timeout values for initial device probing
Currently, we have very long timeouts for the initial probing
commands. However, these are not appropriate for modern (post 2010) SCSI
disks. Sandards since SPC3 state that these commands should not wait for
media access. Since we retry them several times during the initial bus
scan, these delays can delay the boot by minutes (5 minutes per errant
disk in our expereince). These delays don't help and only hurt, so
reduce the TESTUNITREADY, INQUIRY and MODESENSE commands (during the
initial probe). Provide sysctl/tuneables to change the time for these
and also the REPORTLUNS commands for people that might need to adjust
them for devices that violate this belief but none-the-less work with
longer timeouts.
kern.cam.tur_timeout (default was 60s, now 1s)
kern.cam.inquiry_timeout (default was 60s, now 1s)
kern.cam.reportluns_timeout (default is 60s)
kern.cam.modesense_timeout (default was 60s, now 1s)
This can be partially merged: the sysctls can, but the new defaults likely
shouldn't.

[clang-doc] Serialize the global namespace name in JSON (#171701)
Previously, the global namespace's "Name" field was left empty. It could
be identified this way, but it could also be identified by its USR.
Actually populating the "Name" field allows for nicer output in the
future.
VectorCombine: Improve the insert/extract fold in the narrowing case
Keeping the extracted element in a natural position in the narrowed
vector has two beneficial effects:
1. It makes the narrowing shuffles cheaper (at least on AMDGPU), which
allows the insert/extract fold to trigger.
2. It makes the narrowing shuffles in a chain of extract/insert
compatible, which allows foldLengthChangingShuffles to successfully
recognize a chain that can be folded.
There are minor X86 test changes that look reasonable to me. The IR
change for AVX2 in llvm/test/Transforms/VectorCombine/X86/extract-insert-poison.ll
doesn't change the assembly generated by `llc -mtriple=x86_64-- -mattr=AVX2`
at all.

AMDGPU/PromoteAlloca: Refactor into analysis / commit phases
This change is motivated by the overall goal of finding alternative ways
to promote allocas to VGPRs. The current solution is effectively limited
to allocas whose size matches a register class, and we can't keep adding
more register classes. We have some downstream work in this direction,
and I'm currently looking at cleaning that up to bring it upstream.
This refactor paves the way to adding a third way of promoting allocas,
on top of the existing alloca-to-vector and alloca-to-LDS. Much of the
analysis can be shared between the different promotion techniques.
Additionally, the idea behind splitting the pass into an analysis
phase and a commit phase is that it ought to allow us to more easily make
better "big picture" decision about which allocas to promote how in the
future.

NAS-138885 / 26.04 / Replace usage of `select.select` in webshell_app.py (#17808)
We avoid the use of this function since it can fail for large file
descriptors.
[MemProf] Add option to emit full call context for matched allocations (#170516)
Add the -memprof-print-matched-alloc-stack option to enable emitting the
full allocation call context (of stack ids) for each matched allocation
reported by -memprof-print-match-info. Noop when the latter is not
enabled.
[clang-doc] Add JSON bools for parents, vparents and test (#171699)
Parents and virtual parents didn't have "Has" bools in JSON output. That
made it difficult to only create output conditionally.
Also add an explicit test for inheritance and parents, vparents, and
bases which actually weren't tested in JSON
llvm: Add missing `LLVM_ABI` annotations (#171629)
This patch updates various LLVM headers to properly add the `LLVM_ABI`
and `LLVM_ABI_FOR_TEST` annotations to build LLVM as a DLL on Windows.
This effort is tracked in #109483.

InstCombine: Fold ldexp with constant exponent to fmul (#171731)
If we can represent this with an fmul, prefer it as a canonical
form. More optimizations will understand fmul, and allows contract to
fma.
