[LoongArch] Support ISD::SET_ROUNDING (llvm.set.rounding) (#206395)
Fix https://github.com/llvm/llvm-project/issues/205039.
The LoongArch FCSR RM field supports four rounding modes, whose
encodings differ from LLVM's rounding mode values:
FCSR: 0=RNE, 1=RZ, 2=RP, 3=RM
LLVM: 0=RTZ, 1=RNE, 2=RUP, 3=RDN
For LLVM rounding mode 4, round to nearest with ties away from zero,
diagnose an error when it is a constant.

ktls: Add a tunable to disable TLS receive
TLS receive offload is really only beneficial for in-kernel use cases
(such as NFS over TLS) or when using a hardware offload. In addition,
several recent SAs have involved the TLS receive path, but the only
current mitigation for those is to disable TLS offload entirely.

[AMDGPU] Introduce ABI occupancy for object linking
This PR introduces ABI occupancy as the contract used to compile functions under
object linking. The default is derived from the occupancy needed for a 1024
workitem workgroup, can be overridden with `-amdgpu-abi-waves-per-eu`, and can
be overridden per function by `amdgpu-flat-work-group-size` or tightened by an
accepted `amdgpu-waves-per-eu` hint.
The backend emits the selected occupancy in `.amdgpu.info` and uses it to
enforce the object linking register budget.
[RFC][AMDGPU][lld] Add object linking support
Add AMDGPU ELF object-linking support in lld, including resource propagation,
LDS layout, indirect-call handling, named-barrier updates, target compatibility
checks, and kernel descriptor/metadata patching.
This is a large PR because the linker needs to understand and validate several
AMDGPU object-linking concepts end to end. I tried to keep the changes scoped to
the necessary linker support and related metadata plumbing, but I'm open to
suggestions on how to split or structure the review to make it easier.

[HLSL] Enable conversion of ConstantBuffer<T> to T (#205996)
HLSL allows assigning a `ConstantBuffer<T>` to an object of type `T`.
This change adds support for this.

asmc: try PIO before MMIO to avoid false T2 detection
Add hw.asmc.system-state and hw.asmc.board-id read-only sysctls to
expose the T2 system state register and Mac board identifier via SMC.
Try PIO access before MMIO during probe to prevent false T2 detection
on Macs that happen to have something mapped at the T2 BAR address.

net80211: fix CCMP/GCMP AAD for MFP frames
Update ieee80211_crypto_init_aad() to do what 802.11-2020 says -
only mask fc[0] bits 4-6 on data frames, not on management frames.
This (with other diffs to actually negotiate MFP and configure
ath(4) for MFP + software keys) allows the CCMP path to decrypt
CCMP MFP frames in the software path.

Introduce EFIKA_OFW_WORKAROUNDS - patch OFW trampoline for EFIKA.
Long story short, is that SmartFirmware (EFIKA's OpenFirmware) misbehaves
on every OF call from the kernel by zeroing SDR1 and messing with BATs.
In the olden days, these problems were worked around with FIRMWORKSBUGS
option. However, that option does not work currently on EFIKA. Presumaly,
something has changed between 2012 and now, which causes FIRMWORKSBUGS
to hang on SmartFirmware very early (before NetBSD copyright banner is
printed).
So we get this kludge, which only does the bare minimum to let OFW
call succeed, and the kernel continue after the call.
