[VectorCombine] Fold vector.reduce.OP(F(X)) == 0 -> OP(X) == 0 (#173069)
This commit introduces a pattern to do the following fold:
vector.reduce.OP f(X_i) == 0 -> vector.reduce.OP X_i == 0
In order to decide on this fold, we use the following properties:
1. OP X_i == 0 <=> \forall i \in [1, N] X_i == 0 1'. OP X_i == 0 <=>
\exists j \in [1, N] X_j == 0
2. f(x) == 0 <=> x == 0
From 1 and 2 (or 1' and 2), we can infer that
OP f(X_i) == 0 <=> OP X_i == 0.
For some of the OP's and f's, we need to have domain constraints on X to
ensure properties 1 (or 1') and 2.

Bump __FreeBSD_version to 1600011 after changes to eventfd
This covers the commits that updated the API and the commit that exposes
that API in linuxkpi for DRM drivers.

linuxkpi: Add eventfd_*()
Add <linux/eventfd.h> and expose the `eventfd_*()` API. This is used by
DRM drivers for some time, but the code was commented out so far.
Note that Linux uses `struct eventfd_ctx`, but FreeBSD defines `struct
eventfd`. We define `eventfd_ctx` as a synonym to `eventfd`.

eventfd: Add eventfd_signal()
The `eventfd_signal()` function is the equivalent to a write to an
eventfd file descriptor: it bumps the internal counter and wakes up
processes waiting for it.
`eventfd_signal()` is meant to be used by kernel drivers. DRM drivers
will call it through linuxkpi.

eventfd: Add refcounting
An eventfd file descriptor can be used by drivers such as DRM drivers
through linuxkpi. A driver can hold a reference to such a file
regardless of the fact it is used by userland or not.
This patch introduces a refcount in `struct eventfd`, plus the
`eventfd_get()` and `eventfd_put()` functions to acquire and release
references. These functions will be used by DRM drivers for instance.
This structure is internal to `sys/kern/sys_eventfd.c` and not used
anywhere else. Thus it is safe to add a field without breaking anything.

net/liferea: unbreak after 66d6d48a3884
The code assumed that with pygobject > 3.52 we'd also have
glib > 2.86 - but at the time of this commit, we have only
glib 2.84.4. On the downside, this needs to be revisited once
glib is updated.
sysutils/fastfetch: update to 2.58.0
# upstream changes
# 2.58.0
An early release to fix compatibility issues with KDE Plasma 6.6.
Breaking changes:
* The `de.slowVersionDetection` option has been removed. Slow version
detection is now always enabled, as required on non-FHS-compliant
distros (e.g., NixOS). (#2149, DE, Linux)
Features:
* Adds the `--structure-disabled <modules...>` command-line flag to temporarily disable module structure printing.
* For example: `fastfetch --structure-disabled colors` removes the color blocks from the default output.
* Supports chassis type detection on Linux ARM devices when reported via the device tree (Chassis, Linux)
* Supports Bedrock Linux version detection (#2155, OS, Linux)
