[MLIR] Add `IntegerDivisibilityAnalysis` and `InferIntDivisibilityOpInterface` (#197728)
This patch is a port from
https://github.com/iree-org/iree/blob/main/compiler/src/iree/compiler/Dialect/Util/Analysis/IntegerDivisibilityAnalysis.cpp
to upstream
It introduces a dataflow analysis that tracks integer divisibility
(divisor + remainder lattice) for SSA values, plus an op interface
`InferIntDivisibilityOpInterface` for ops to participate.
It adds:
* `IntegerDivisibilityAnalysis` produces a `Divisibility` lattice
`{divisor, remainder}`
* `InferIntDivisibilityOpInterface` interface
* External-model implementations for `arith` and `affine` ops
* `test-int-divisibility` test pass + lit tests
Example:
Here is the usual approach to laod element `i` from `i4` buffer emulated

[flang][acc] Accept component of global variable in `acc declare` (#197819)
This MR partially extends the current implementation to accept cases of
`acc declare` on a `parent%comp` whenever the `parent` has been `acc
declare`d with the same clause. This is done by generating only the acc
global constructor only for mapping the parent as the child is expected
to be part of parent.
The limitations still remain as a TODO unless it can be proven parent is
mapped. A generic implementation would need either compiler generated
ordering on the global constructors used for mapping or runtime managed
ordering.
[AArch64] Do not pass debug insn to liveness analysis (#198021)
Fix another stepBackward location.
Debug instructions must not affect liveness analysis. stepBackward has
an assertion failure on debug instructions after

[flang][NFC] Finishing touches on legacy lowering conversion (#197973)
At the beginning of legacy lowering conversion, some tests were
initially converted to emit FIR. After some discussion, it was decided
to revisit those tests and convert them to emit HLFIR. This change
completes that step and should be the final change in removing vestiges
of legacy lowering.

[lldb] Avoid unnecessary strlen of mangled names in ConstString (NFC) (#197995)
C++ mangled names are known to be quite long at times. This change makes
use of available length data, instead of using the `StringRef(const char
*)` constructor which calls `strlen`.
The main detail is to replace `selectPool(llvm::StringRef(raw))` with a
call to `selectPool` using a readily available StringRef.
net80211: define a type for rssi values
Due to net80211 keeping values in 0.5dBm relative to the noise floor
an int8_t is not good enough to prevent a double wrap around, which
means the reported rssi values can be wrong (see D50928 or likely
a commit in the future for more information).
In order to address the problem and not break the userspace API,
start by defining a type within the kernel and use that. In a
next step we will then update the int8_t to int16_t to avoid the
problem up to the ioctl code. This will then allow us to work
on the the user space API indepedently (see PR 293016 for possible
impact outside the base system).
No functional changes intended.

wtap: use typed rssi and noise floor values
Adjust the rssi and nf arguments to typed int8_t and adjust the maths
for rssi to be consistant with what net80211 expects.
