4b776ae441 std.Progress: fix race assertion failure
A node may be freed during the execution of this loop, causing there to
be a parent reference to a nonexistent node. Without this assignment,
this would lead to the map entry containing stale data. By assigning
none, the child node with the bad parent pointer will be harmlessly
omitted from the tree.

Closes #20262

spirv: new vectorization helper
The old vectorization helper (WipElementWise) was clunky and a bit
annoying to use, and it wasn't really flexible enough.

This introduces a new vectorization helper, which uses Temporary and
Operation types to deduce a Vectorization to perform the operation
in a reasonably efficient manner. It removes the outer loop
required by WipElementWise so that implementations of AIR instructions
are cleaner. This helps with sanity when we start to introduce support
for composite integers.

airShift, convertToDirect, convertToIndirect, and normalize are initially
implemented using this new method.

spirv: change direct vector child repr to direct
Previously the child type of a vector was always in indirect representation.
Concretely, this meant that vectors of bools are represented by vectors
of u8.

This was undesirable because it introduced a difference between vectorizable
operations with a scalar bool and a vector of bool. This commit changes the
representation to be the same for vectors and scalars everywhere.

Some issues arised with constructing vectors: it seems the previous temporary-
and-pointer approach does not work properly with vectors of bool. To work around
this, simply use OpCompositeConstruct. This is the proper instruction for this,
but it was previously not used because of a now-solved limitation in the
SPIRV-LLVM-Translator. It was not yet applied to Zig because the Intel OpenCL
CPU runtime does not have a recent enough version of the translator yet, but
to solve that we just switch to testing with POCL instead.

spirv: disable tests that fail on pocl
Besides the Intel OpenCL CPU runtime, we can now run the
behavior tests using the Portable Computing Language. This
implementation is open-source, so it will be easier for us
to patch in updated versions of spirv-llvm-translator that
have bug fixes etc.

d4bc64038c Zir: remove legacy error_set_decl variants
These instructions are not emitted by AstGen. They also would have no
effect even if they did appear in ZIR: the Sema handling for these
instructions creates a Decl which the name strategy is applied to, and
proceeds to never use it. This pointless CPU heater is now gone, saving
2 ZIR tags in the process.

ec337051a9 Fix slight deviation from spec in handling Elf*_Rela relative relocations
`Elf*_Rela` relocations store their argument in `r_addend`, including for `R_*_RELATIVE` relocations.  Unlike `Elf*_Rel` relocations, they are not applied as a delta to the destination virtual address.  Instead, they are computed from `base_address + r_addend` directly.

45b62c4529 io_uring: don't assume completions order
We are posting two submission (zero copy send and receive) and then
reading two completions. There is no guarantee that those completions
will be in the order of submissions.
This test was expecting fist send completion then receive.
Fix is allowing them to come other way too.

0884a43411 CMake: remove -Dstd-docs=false flag when building stage3
This now defaults to false already since the autodocs rework.

The langref still cannot be enabled by default because the langref
contains doctests that exercise the `@cImport` feature which is disabled
in zig2 builds.

ed795a907d target.zig: Constrain aarch64 to glibc version 2.17 or later
Had constrained the `aarch64_be` target, but not `aarch64`.  This
constraint is necessary because earlier versions of glibc do not support
the aarch64 architecture.

Also, skip unsupported test cases.

8bee879fc2 test/link/glibc_compat: Add C test case for glibc versions
glibc_runtime_check.c is a simple test case that exercises glibc functions
that might smoke out linking problems with Zig's C compiler.  The
build.zig compiles it against a variety of glibc versions.

Also document and test glibc v2.2.5 (from 2002) as the oldest working
glibc target for C binaries.

d8fffee3fb glibc: restore "weak_hidden_alias" macro for older glibc versions
The fstat,lstat,stat,mknod stubs used to build older (before v2.33)
glibc versions depend on the weak_hidden_alias macro.  It was removed
from the glibc libc-symbols header, so patch it back in for the older
builds.

5293bdfe63 glibc patch: get correct files compiled into libc_nonshared.a
The scope of libc_nonshared.a was greatly changed in glibc 2.33 and
2.34, but only the change from 2.34 was reflected so far. Glibc 2.33
finally switched to versioned symbols for stat functions, meaning that
libc_nonshared.a no longer contains them since 2.33. Relevant files were
therefore reverted to 2.32 versions and renamed accordingly.

This commit also removes errno.c, which was probably added to
libc_nonshared.a based on a wrong assumption that glibc/include/errno.h
requires glibc/csu/errno.c. In reality errno.h should refer to
__libc_errno (not to be confused with the public __errno_location),
which should be imported from libc.so. The inclusion of errno.c resulted
in wrong compile options as well; this commit fixes them as well.

fd8b50ca5c glibc patch: remove some static asserts from fstatat
These are tripping on 32-bit x86 but are intended to prevent glibc
itself from being built with a bad configuration. Zig is only using this
file to create libc_nonshared.a, so it's not relevant.

82ec333f27 glibc patch: don't check __LIBC macro
This is the only place in all of glibc that this macro is referenced.
What is it doing? Only preventing fstatat.c from knowing the type
definition of `__time64_t`, apparently.

Fixes compilation of fstatat.c on 32-bit x86.

4c068c3be1 glibc patch: inline x86-lp_size.h
I could have just included the file from upstream glibc, but it was too
silly so I just inlined it. This patch could be dropped in a future
glibc update if desired. If omitted it will cause easily solvable
C compilation failures building glibc nonshared.

9e76385afc glibc patch: add backwards compatibility for some symbols
- `fcntl` was renamed to `fcntl64` in glibc 2.28 (see #9485)
- `res_{,n}{search,query,querydomain}` became "their own" symbols since
  glibc 2.34: they were prefixed with `__` before.

This PR makes it possible to use `fcntl` with glibc 2.27 or older and
the `res_*` functions with glibc 2.33 or older.

These patches will become redundant with universal-headers and can be
dropped. But we have to do with what we have now.

a4a88e441f glibc patch: version-gate _DYNAMIC_STACK_SIZE_SOURCE
This is a patch to glibc features.h which makes
_DYNAMIC_STACK_SIZE_SOURCE undefined unless the version is >= 2.34.

This feature was introduced with glibc 2.34 and without this patch, code
built against these headers but then run on an older glibc will end up
making a call to sysconf() that returns -1 for the value of SIGSTKSZ
and MINSIGSTKSZ.
