[SSAF] Filter out type-constrained pointers from all reachable unsafe pointers
Integrate the TypeConstrainedPointers analysis results into
UnsafeBufferReachableAnalysis. The final result is filtered with
type-constrainted pointers.
The pointer flow graph is untouched. Removing type-constrained
pointers from the graph will introduce unsoundness.

[compiler-rt][GWP-ASan] Use no-op backtrace if execinfo.h missing (#201266)
Guard backtrace_linux_libc.cpp with __has_include(<execinfo.h>) so that
targets without it (e.g. musl libc) get null stubs instead of a build
failure.
ena: Put taskqueues into correct domain if !RSS
When compiled without 'options RSS', the ena driver created taskqueues
using taskqueue_start_threads_cpuset passing a mask value of NULL,
both in the ena_setup_tx_resources path (for enqueues) and in the
ena_create_io_queues path (for the completion-processing).
In the default configuration, on most EC2 instances, this results in
taskqueues running in the right NUMA domain, but only by accident; in
non-default configurations (e.g. with with multiple EBS volumes
attached and associated NVMe taskqueues) the taskqueues may land in
the wrong NUMA domain even on instance types where the one-EBS-one-ENA
case produces the desired results.
Set (struct ena_que)->domain and use that to inform the choice of CPU
sets. On a c8gn.48xlarge EC2 instance this doubles throughput on a
32-TCP-stream benchmark.

[lldb/script] Add scripted extension base-class templates for hooks and breakpoint resolvers (#209311)
This patch adds the Python base-class templates for `ScriptedHook` (a
unified base class that backs both `target hook add -P` and `target
stop-hook add -P`) and `ScriptedBreakpointResolver`, and wires them into
the Python bindings and docs CMake so every scriptable extension kind
has a template that the docs and future tooling can introspect.
The `ScriptedHook` template unifies what used to require separate
subclasses for target hooks and stop hooks: subclasses implement
`handle_stop` (required, so any hook is a valid stop-hook) and
optionally `handle_module_loaded` / `handle_module_unloaded`, which only
fire for hooks registered via `target hook add -P`.

[BPF] Split stack argument psuedo expansion into a separate pass
This will make the NewPM implementation cleaner given now the two passes
are either required/optional rather than like BPFMIPreEmitPeepholePass
before, which was partially required (for stack argument psuedo
expansion), and optional for other peephole optimizations. I think this
is also a cleaner design in general.
