[llubi] Add basic support for icmp, terminators and function calls (#181393)
Note: icmp with integers is also introduced in this patch, as it is
needed to compute branch conditions.
HBSD: ASLR: Use VMFS_NO_SPACE to map the stack
We want the stack to land where we calculated it based on the
precalculated delta. While VMFS_ANY_SPACE still gets the job done, it is
the wrong flag in this case. By using VMFS_NO_SPACE, we make the process
of mapping the stack a quicker operation.
However, the risk of a failed mapping increases since vm_map_find(9)
will fail if the requested virtual address is already allocated. The
risk of this is small since we're dealing with a fresh address space.

HBSD: Disable WITNESS' checking of vnode locks
FreeBSD relatively recently changed how vnode locking works in the
kernel. There are a few places that still need to be updated.
HardenedBSD's use of filesystem extended attributes seems to trip
WITNESS vnode lock checking when ZFS is used. This causes a kernel
panic, which is more likely to be triggered during a package build.
So, for now, let's disable the vnode lock checks. I plan to revisit this
when I have more available time.

[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`.
Added textproc/php-pecl-spell version 1.0.1
PHP is a programming language designed to be embedded into web pages.
This module provides support for pspell (spell checking) for PHP >= 8.4.0
For earlier PHP versions, use textproc/php-pspell
[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.
