[X86] Make WinEH crash test reliable under ASan (#212820)
The WinEH unwind `v2 error` test uses `not --crash` for malformed MIR
inputs.
In AddressSanitizer builds, the default `abort_on_error=0` can prevent
the
expected fatal error from being reported as a crash, causing FileCheck
to
receive no diagnostic output.
Set `ASAN_OPTIONS=abort_on_error=1` for the expected-crash invocations
in
`win64-eh-unwindv2-errors.mir`.
## Testing
- ASan build focused test passes.
- Non-ASan build focused test passes.
- Five additional serial ASan reruns pass.

e1000: Update shared igb SR-IOV code
Update the shared e1000 PF/VF mailbox interfaces for an in-tree igb
SR-IOV implementation.
Intel FreeBSD igb-2.5.31 and DPDK provide the older PF/VF mailbox
baseline.
The retained PF mailbox read and explicit unlock operation follow a
simple Linux igb parameter addition to make PF mailbox acquisition
nonblocking so the driver can retry outside the shared primitive.
Treating a CTS-less E1000_PF_CONTROL_MSG as a reset follows DPDK.

iflib: Add restart transactions for IOV reconfiguration
Some devices remap the PF queues when entering or leaving SR-IOV. Add
opt-in PCI IOV helpers that hold the iflib context lock across the
complete stop, driver callback, and restart transaction.
Existing drivers continue to use the non-restarting helpers.

[CIR][CUDA] Add support for NVVM xchg builtins (#211815)
Adds codegen support for the scoped and unscoped NVVM atomic exchange
builtins:
`atom_xchg,` `atom_cta_xchg,` and `atom_sys_xchg.`
These are lowered to the corresponding CIR `cir.atomic.xchg` operations
and subsequently lowered to LLVM `atomicrmw xchg` instructions.
[CIR] Implement complex rvalues NYI (#211645)
emitReturnOfRValue had an NYI for _Complex types, so returning one as an
Rvalue (see example of a lambda invoker) would NYI. Since the logic to
the store is already handled in the lower-to-LLVM, this ended up being a
pretty trivial patch.
Note; There are some differences in how this lowers, because our calling
convention for the ret is different here, and we maintain the 'complex'
type differently even through LLVM-IR. However, the IR looks to be
equivilent.
[MacroFusion] Add SDep param to predicates(NFC) (#212255)
This patch aims to extend the API for macro fusion predicates with an
additional SDep param which allows each predicate to individually decide
wether a pair should be macro fused based on the kind of dependency
between the 2 instructions.
A followup patch https://github.com/llvm/llvm-project/pull/212603
introduces a real user in AArch64.
[HLSL] Add sema for use of samplers and gathers on textures of doubles and ints (#212613)
Fixes https://github.com/llvm/llvm-project/issues/198882 and
https://github.com/llvm/llvm-project/issues/198883
This PR:
- Implements sema checks to reject the use of samplers and gathers on
textures of doubles.
- Implements sema checks to reject use of samplers on textures of
integers before shader model 6.7

[flang][cuda] Unify registration under -gpu=mem:unified (#212871)
Always use the cuf operation under -gpu=unified as registration might be
differed to the backend. Add a UnitAttr to distinguish device resident
variable that will not use cudaRegisterHostVar but cudaRegisterVar.
[flang][cuda] Keep data transfers for allocatable assignments with device data (#212855)
An assignment to a whole allocatable was lowered as a host assignment to
keep reallocation semantics, without checking the memory kind, so a
device allocatable assigned from a managed array wrote device memory
from the host and segfaulted.
Keep the transfer when either side is device or constant data. CUDA
Fortran Programming Guide 3.4.1 makes an assignment between managed and
device data a copy in both directions, with no exception for an
allocatable left-hand side.
[CIR] Allow boolean operands in cir.cmp (#206846)
GROMACS uses scoped enums with a boolean underlying type as type-safe
flags (`enum class EmulateGpuNonbonded : bool`), and compares them with
`==` / `!=` / `<`. A scoped enum is not integer-promoted before the
comparison, so the operand reaches `cir.cmp` as a `!cir.bool` (CIR
already
represents a boolean-underlying enum with `!cir.bool`). The `cir.cmp`
operand constraint `CIR_ComparableType` does not list bool, so module
verification fails before the CIR-to-CIR passes with:
```
'cir.cmp' op operand #0 must be comparable type, but got '!cir.bool'
```
Add bool to `CIR_ComparableType` and let the comparison lowering compare
`!cir.bool` the same way it already compares pointers, as an unsigned
`icmp` (`ult` for `<`), which is what classic CodeGen does with these as
`i1`. Plain `bool` comparisons are unchanged, since they still carry the

[NFC][analyzer] Remove BlockEdge parameter of processCFGBlockEntrance (#212804)
As a side effect of my previous refactoring efforts, the method
`ExprEngine::processCFGBlockEntrance` had two very similar parameters: a
`BlockEdge` and a `BlockEntrance` instance.
These are both subclasses of `ProgramPoint`, stored the same data (the
`BlockEntrance` was initialized with data taken from the `BlockEdge`
just before the call) and the `BlockEdge` was almost completely unused
within `processCFGBlockEntrance`.
The only reason for having the `BlockEdge` was that it was stored in the
debug statistic table `blocksExhausted`; so this commit transitions that
simple debug code to use `BlockEntrance` instances instead (which is
also perfectly sufficient for its goals). This allows the removal of the
redundant argument of `processCFGBlockEntrance`.
This prepares the ground for further cleanup in this method.
[CIR] Add fenv attribute to more builtins (#212880)
This adds the #cir.fenv attribute to the CIR_UnaryFPToIntBuiltinOp and
CIR_TernaryFPToFPBuiltinOp base classes, and through them to the
cir.lround, cir.llround, cir.lrint, cir.llrint, and cir.fma operations.
This attribute is still missing from various cast and compare
operations. Those will be added in a follow-up change.
