[KnownFPClass] Add trunc/floor/ceil and fix ppcf128 demanded classes (#229982)
Adds `KnownFPClass` functions for `trunc`, `floor`, and `ceil`. Also
corrects the `DemandedSrcMask` code for `PPCDoubleDouble` in
`SimplifyDemandedUseFPClass` for the integer-rounding functions.
I've only added basic deductions for `PPCDoubleDouble` for now:
- `trunc(x)` is only `+-inf` if `x == +-inf` (we already had this)
- `floor(x)` is only `+inf` if `x == +inf`
- `ceil(x)` is only `-inf` if `x == -inf`
AI disclosure:
I used Claude Opus 5 to help write the code and tests.
epoch: Queue drain callbacks from each CPU's callback task
epoch_drain_callbacks() bound the calling thread to each CPU in turn
to queue a callback on that CPU's record. Callers are often user
threads, such as kldunload or ifconfig destroy, and ULE does not
preempt a CPU-bound thread for a migrating thread of no better
priority, so each bind could wait out a time slice. On an 8-CPU VM
with six busy loops running, destroying an epair interface took 1.5 s
and kldunload pflow 0.8 s.
Instead, set a request flag on each record and enqueue that CPU's
callback task, which queues the callback before it polls the record.
The task runs on the CPU's softirq gtaskqueue thread at PI_SOFT, which
preempts a busy user thread, so the request is served at once; the
caller no longer migrates. Both operations now take under 10 ms, idle
or under load.

[llvm-readobj] Test call graph callees below and above four
Add a function with fewer callees, as the old SmallSet already kept
section order for up to four, and say why main has five distinct
callees. Move main's repeated callee to the end, so that a repeat is
also skipped after the set of seen callees outgrows its inline size.

hooks.sh allow running DebugO{n,ff} from hooks_run
We need to watch out for _debugO{n,ff}_hooks.
Also add add_list (hook lists are just lists).
Fix bug in hooks_has() - should look for $2 in list.

[SCEV] Prove monotonic predicates from loop entry in isKnownViaInduction
isKnownViaInduction requires the predicate to hold on loop entry and on
the backedge. The backedge check usually fails when the latch only
bounds the IV from above, so e.g. {s,+,1}<nsw> >=s 0 is not proven even
when s >=s 0 is known on entry.
In a loop guarded by "start <u len", this keeps IndVars from computing
a[i - 32] in i64.
A monotonically increasing predicate against a loop-invariant value can
only change from false to true, so holding on entry is enough.
Use this in isKnownOnEveryIteration when the backedge check fails.

amiga: booters: Fix boot failure with recent binutils
elf2bb(1) and booters assume that .rodata.str1.1 section precedes .bss,
which is not guaranteed by recent binutils. We put the section just
behind .rodata as done by older binutils.
No release branches are affected.

"More x86 fixes:
- Fix a WARN if the SS bit is set in #NPF exit codes.
The AMD manual is unclear about whether it can be set when the
guest uses CET but the SupervisorShadowStackEn feature (which KVM
does not use) is disabled. However, Hyper-V has started using CET
now that KVM supports GMET (it wants the two feature in pairs), and
that dissolves all the doubts: the SS bit *is* reported and not
clearing it causes a WARN and/or a UBSAN splat.
- If creating a vCPU ultimately fails, clear its entry in the AVIC
