[mlir][arith] Preserve unsigned values when narrowing operations
Require unsigned representability for divui, ceildivui, remui, and shrui.
A signed range fitting the narrower type does not preserve the unsigned
operand values, even when the result fits.
Add concrete counterexamples and coverage for safe narrowing of
zero-extended and proven nonnegative operands.
iwn: fix TX QoS AC -> TID mapping for A-MPDU selection
Map the packet QoS value to a TID before looking it up in the
per node + TID AMPDU state array.
The TX A-MPDU state used to be per-AC, but I changed it to be
per-TID because it /is/ negotiated per-TID. However this is
not aligned correctly and A-MPDU on eg the voice queue would
cause a mismatch and thus packets to get dropped.
(TIDs 8..15 are special and session based, not traffic QoS based.)
I noticed this because "ssh host" failed after a while, but
"telnet host 22" succeeded. It turned out that frames weren't
making it to the driver transmit path and I traced it
back to being dropped here. Traffic worked for a while until
A-MPDU TX was negotiated, and then all traffic on a TID
would fail until the 802.11 association was re-established.

[SLP] Handle REVEC when costing expanded compress mask
With REVEC the scalars are vectors. The masked-load-compress shuffle that is
emitted uses the compress mask expanded to the elements of those vectors
(transformScalarShuffleIndiciesToVector), but the cost was computed with the
unexpanded per-vector mask, so a shuffle such as <24 x i8> -> <16 x i8> was
costed as a <2 x i8> shuffle. This made the compress sequence looked cheaper
than it is.

httpd: Fix "server match" configuration blocks
The return value of str_find() as used in SRVFLAG_SERVER_MATCH was not
checked at all. This meant any "server match" block behaved like a
wildcard.

[flang][OpenMP] Switch clause verification to descriptor-based
Delete all the scattered pieces of clause verification that are now
replaced by the unified handling.
[flang][OpenMP] Improve diagnostics about modifier properties
Use OpenMPDeprecated and OpenMPFuture warning categories for modifier
diagnostics as well, analogously to how they are used for clauses.
[flang][OpenMP] Account for using different versions for modifier checks (#229525)
When a modifier from a past/future version is accepted, use its
properties
from the nearest version in which it is allowed.
[flang][OpenMP] Create generic interfaces for "container" entities (#229524)
In short, clauses are containers of modifiers, and directives are
containers of clauses. With the abstractions in place, clauses and
modifiers look almost the same from the point of view of syntactic
properties.
Use these functions to implement generic GetAllowedElements and
GetElementVersionRange functions.
[IR] Reject IR functions that have hot and cold attributes (#233298)
These are mutually exclusive and clang already enforces this. We should
just reject this in the verifier so that passes don't have to think
about precedence of these two attributes.
