[RFC][IR] Remove `Constant::isZeroValue` (#181521)
`Constant::isZeroValue` currently behaves same as
`Constant::isNullValue` for all types except floating-point, where it
additionally returns true for negative zero (`-0.0`). However, in
practice, almost all callers operate on integer/pointer types where the
two are equivalent, and the few FP-relevant callers have no meaningful
dependence on the `-0.0` behavior.
This PR removes `isZeroValue` to eliminate the confusing API. All
callers are changed to `isNullValue` with no test failures.
`isZeroValue` will be reintroduced in a future change with clearer
semantics: when null pointers may have non-zero bit patterns,
`isZeroValue` will check for bitwise-all-zeros, while `isNullValue` will
check for the semantic null (which
may be non-zero).
[clang][Python] Use str.format instead of string concatenations (#173861)
This PR replaces string concatenations and the older `%` string
interpolation with `str.format`. Changes along those lines were
originally a part of #173845, but they were moved to a new PR,
where it was decided that `str.format` is preferable over
f-strings.
Changes in this commit are identical to
abf1d0bea04ab5d5ed1be3708ce1cd86707d5c8f, but commit title and
description were changed to correctly reflect the changes.
Revert "[clang][Python] Use fstrings instead of string concatenations (#173861)"
This reverts commit abf1d0bea04ab5d5ed1be3708ce1cd86707d5c8f,
because its title and description are entirely wrong.
f-strings is what was initially proposed, but then it was decided
to go with `str.format`.
[clang] Add explicit std::move(...) to avoid a few copies (#180478)
Moving an std::shared_ptr is always profitable (marginally).
Moving a clang::LayoutOverrideSource::Layout may be profitable depending
on the size of the underlying llvm::SmallVector.
Changes suggested by performance-use-std-move from #179467

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"Not much changed in the clk framework this time except the clk.h
consumer API moved the context saving APIs around to fix a build error
in certain configurations.
There was a change to the core framework for CLK_OPS_PARENT_ENABLE
behavior during registration, but it wrecked existing drivers that
didn't expect things to be turned off during clk registration so it
got reverted.
This cycle is really a large collection of new clk drivers, primarily
for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
Another big change in here is support for automatic hardware clock
gating on Samsung SoCs where the clks turn on and off when needed.
Ideally more vendors move to this method for better power savings. The
highlights are in the updates section below.

multimedia/uxplay: import uxplay-1.73.3
Packaged by Brian Callahan in PR 60007
(with some fixes by myself).
UxPlay is an open source AirPlay2 Mirror server. Its main use is to
act like an AppleTV for screen-mirroring (with audio) of
iOS/iPadOS/macOS clients (iPhone, iPod Touch, iPad, Mac computers)
in a window on the server display of a host running Linux, macOS,
other Unix, or Microsoft Windows.
The UxPlay server and its client must be on the same local area
network, on which a Bonjour/Zeroconf mDNS/DNS-SD server is also
running (only DNS-SD "Service Discovery" service is strictly
necessary, it is not necessary that the local network also be of the
".local" mDNS-based type). On Linux and BSD Unix servers, this is
usually provided by Avahi, through the avahi-daemon service.

[VPlan] Add VPSymbolicValue for UF. (NFC)
Add a symbolic unroll factor (UF) to VPlan similar to VF & VFxUF that
gets replaced with the concrete UF during plan execution, similar to how VF
is used for the vectorization factor. This is a preparatory change that
allows transforms to use the symbolic UF before the concrete UF is
determined.
Note that the old getUF that returns the concrete UF after unrolling has
been renamed to getConcreteUF.
