[lldb][Module] Only call LoadScriptingResourceInTarget via ModuleList (#190136)
This patch is motivated by
https://github.com/llvm/llvm-project/pull/189943, where we would like to
print the "these module scripts weren't loaded" warning for *all*
modules batched together. I.e., we want to print the warning *after* all
the script loading attempts, not from within each attempt.
To do so we want to hoist the `ReportWarning` calls in
`Module::LoadScriptingResourceInTarget` out into the callsites. But if
we do that, the callers have to remember to print the warnings. To avoid
this, we redirect all callsites to use
`ModuleList::LoadScriptingResourceInTarget`, which will be responsible
for printing the warnings.
To avoid future accidental uses of
`Module::LoadScriptingResourceInTarget` I moved the API into
`ModuleList` and made it `private`.

truss: add support for decoding Netlink messages
Netlink usage is growing in FreeBSD. This patch adds support to
`truss(1)` to decode Netlink headers in sendmsg/recvmsg calls, making
debugging network configuration tools significantly easier.
Changes:
libsysdecode: Add `sysdecode_netlink()` to parse struct `nlmsghdr`.
truss: Detect `AF_NETLINK` sockets and decode the message payload.

[mlir][reducer] Remove the restriction that OptReductionPass must be a ModuleOp (#189038)
This PR aims to make the pass more generic by removing the ModuleOp
restriction. This PR reimplements the logic using a standalone
PassManager. Additionally, the isInteresting method has been updated to
accept Operation* for better flexibility. Finally, a dedicated test
directory has been added to improve the organization of OptReductionPass
tests.
[AMDGPU] Add !noalias metadata to mem-accessing calls w/o pointer args (#188949)
addAliasScopeMetadata in AMDGPULowerKernelArguments skips instructions
with empty PtrArgs, including memory-accessing calls that have no
pointer arguments (e.g. builtins like threadIdx()). Because these calls
never receive !noalias metadata, ScopedNoAliasAA cannot prove they don't
alias noalias kernel arguments. MemorySSA then conservatively reports
them as clobbers, which prevents AMDGPUAnnotateUniformValues from
marking loads as noclobber, blocking scalarization (s_load) and forcing
expensive vector loads (global_load) instead.
Fix by adding all noalias kernel argument scopes to !noalias metadata
for memory-accessing instructions with no pointer arguments. Since such
instructions cannot access memory through any kernel pointer argument,
all noalias scopes are safe to apply.
This fixes a performance regression in rocFFT introduced by bd9668df0f00
("[AMDGPU] Propagate alias information in AMDGPULowerKernelArguments").

[clang-doc] Prepare Info types for Arena allocation (#190046)
To allocate Info structures directly in an Arena, they cannot have
members with nontrivial destructors, or we will leak memory. Before we
migrate them, we can replace growable vector types with intrusive lists.
This introduces some slight overhead as these types now have new pointer
members for use in ilists in later patches.
