[MLIR][OpenMP] Support cancel taskgroup inside of taskloop
Implementation follows exactly what is done for omp.wsloop and omp.task.
See #137841.
The change to the operation verifier is to allow a taskgroup
cancellation point inside of a taskloop. This was already allowed for
omp.cancel.
[mlir][py] ability to downcast AffineExpr after #172892 (#174808)
AffineExpr is a separate hierarchy of LLVM-style nested classes that
doesn't rely on TypeID and is not extensible. We need the ability to
downcast the Python equivalent of those to a specific subclass that was
seemingly lost in PR #172892. Bring it back by having an explicit cast.
We don't really need user-defined type casters here since AffineExpr is
entirely closed and not typed, unlike values.
InstCombine: Consider not-inf/nan context when simplifying fmul
Consider if the result can be nan, or if the inputs cannot
be infinity from the flag when trying to simplify fmul into
copysign.

[mlir][OpenMP] Lower device clause for target data/enter/exit/update (#174665)
Extend OpenMP device clause lowering for target data, target enter data,
target exit data, and target update to accept non-constant values.
Previously, only constant device IDs could be lowered to LLVM IR.
Add Flang tests to validate device clause handling and mark the feature
as supported in the OpenMPSupport documentation. New tests cover:
- target teams
- target teams distribute
- target teams distribute parallel do
- target teams distribute parallel do simd
- target data
Tests for target update and target enter/exit were
already present in Flang.
[libc++] Refactor poll_with_backoff (#173184)
This patch gets rid of bool result values which were confusing, and
instead replaces them with enum class values describing the meaning of
each return value.
bhyve: improve console error reporting on arm64
Currently, on arm64, if bhyve fails to initialize the console,
it falls into assert(), which does not look particularly pretty
for users.
Replace the assert with proper error handling so bhyve prints
a meaningful error message and exits with status code 4 (error).
That matches the behavior on amd64.

NAS-139203 / 26.04 / Disable SMB3 unix extensions by default (#17971)
This commit disables the SMB3 unix extensions by default. They will be
exposed as a configurable option in a future PR.
