asmc: replace hardcoded model table with universal probing
Probe SMC keys at attach time to detect hardware capabilities,
supporting all Intel Apple machines without per-model entries.
Sensors are discovered by scanning sorted SMC key ranges for
known prefixes and types. Capabilities such as SMS, fan safe
speed, and ambient light are detected by key presence.
A global key description table provides human-readable names
for well-known temperature sensors.
Tested on:
- MacBook Pro (Early 2007, Mid 2014, Mid 2015)
- MacBook Air (Early 2015, Mid 2017)
- iMac (Mid 2011, Late 2013)
- Mac mini (Mid 2011)

[orc-rt] Add NativeDylibManager. (#194792)
NativeDylibManager is an orc_rt::Service that supports loading,
unloading, and lookup of symbols via the system dynamic loader's native
APIs.
The current implementation only supports the POSIX dlfcn.h APIs (dlopen,
dlclose, dlsym), but it should be straightforward to extend to Windows.
powerpc/pic: Add a PIC_AP_INIT() to set up AP PIC info
pc_cpuid may not match the PIC's idea of a given CPU. Since openpic
has a WHOAMI register, we can use that to get the PIC's idea of the CPU.
This needs to be done on each AP, so add a PIC_AP_INIT device method so
the PIC can perform any AP-specific initialization at AP bootstrap time.
This fixes SMP on e6500, which is still lacking SMT support.

powerpc/openpic: Increase the maximum number of IRQs allowed
The Freescale MPIC supports up to 2048 IRQs, but since we only build an
array of 768 interrupts in intr_machdep, clamp the max at 512. The most
any Freescale PowerPC chip actually supports is 452 on the T4240, so 512
is sufficient.
As part of this, increase the vector mask to the full openpic vector
mask, and use this limit as the terminator for the dispatch loop,
instead of a hard-coded 255.

[WebAssembly] Remove WasmEHFuncInfo (NFC) (#194972)
This removes `WasmEHFuncInfo` class.
This class was created to maintain the information of, "If an exception
is not caught by EHPad A, what is its next unwind destination?". Turns
out this information is already in the CFG.
After #130374, we use the common `findUnwindDestination`:
https://github.com/llvm/llvm-project/blob/113479d119a997e4c4c3eae63e087588c9662121/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp#L2107-L2164
Note that in case of `catchswitch`, we follow its unwind destination
chain and add all of them to the invoke BB's successors until it meets a
`cleanuppad`, which always catches an exception. And the order of the
successor is the order of the unwind destination chain. So an invoke
BB's successor list would be like: [normal destination, unwind EHPad 1,
unwind EHPad 2, unwind EHPad 3, ...] where EHPad 2 is the next unwind
destination if EHPad 1 does not catch an exception and so on. So if we
want to know what the current EHPad's next unwind destination is, we can

tcp: release nic ktls send tags when entering time wait
When under heavy load or churn, inline ktls offload NICs may run out
of hardware resources described by ktls send tags. Rather than
waiting for connections to pass through the time_wait state, reclaim
the ktls send tags early, at entry to time_wait. By preventing
potentially tens or hundreds of thousands of sessions from holding
send tags in time_wait, this allows more ktls sessions to be offloaded
to hardware.

[RISCV] Remove isAsmParserOnly from isPseudo instructions. NFC (#194958)
isAsmParserOnly is only used to suppress DecoderEmiter, but that's
already supressed by isPseudo. The real usage for this should be for
instructions that have encoding information but we don't want to
disassemble.
Many of these pseudos are emitted from codegen meaning they aren't
really assembler only. So you can't argue this flag is good for
documentation either.
[RISCV] Remove isAsmParserOnly from LongBccPseudo and LongBcciPseudo. NFC (#194949)
These instructions are created by assembler relaxation. They aren't
"parsed.". isAsmParserOnly suppresses the disassembler for these, but
that was already suppressed by isPseudo and isCodeGenOnly.
IR: Introduce !elf_section_properties for setting section properties.
This new metadata type may be used to set sh_type and sh_entsize on a
global's section. The intent is that it will be used to mark up
CFI jump table sections.
