bhyve: Fix assignment of *niov2 in split_iov()
niov2 returns the number of entries in the iovec starting at offset
"offset". Here we are unconditionally setting it to 1, which of course
isn't right.

[MLIR][XeGPU] Fix XeGPUToXeVM crash on non-integer memref memory spaces (#211053)
## Summary
`convert-xegpu-to-xevm` asserts/crashes when a memref's memory space
isn't an
`IntegerAttr` — e.g. `memref<1024xf32,
#spirv.storage_class<StorageBuffer>>`.
`LoadStoreToXeVMPattern` and `PrefetchToXeVMPattern` compute the LLVM
pointer
address space via the deprecated `MemRefType::getMemorySpaceAsInt()`,
which
asserts on anything but an integer. Memref memory spaces aren't
integer-only
in general (GPU address spaces and XeVM's own `xevm::AddrSpaceAttr` are
both
legal here) — the file's own `isSharedMemRef` already handles this
correctly
elsewhere, these three call sites just didn't.

[CodeGen] Fix -fsanitize=array-bounds for __sized_by / _or_null pointers
`EmitCountedByBoundsChecking()` assumed a CountAttributedType is always
a __counted_by pointer. That isn't true, there are four versions of the
attribute:
* `__counted_by`: Already handled correctly.
* `__counted_by_or_null`: Incorectly handled.
* `__sized_by`: Incorreclty handled.
* `__sized_by_or_null`: Incorreclty handled.
In particular:
* __sized_by / __sized_by_or_null: the loaded bound is a byte count, but the
element index was compared against it directly, so an access was only
flagged once the index exceeded the byte count -- missing out-of-bounds
accesses for a pointee larger than one byte. Scale the index to bytes
('index * sizeof(element)') before comparing. counted_by counts elements
and is unchanged; a void (or otherwise zero-sized) pointee uses the GNU
