[Polly] Forward VFS from PassBuilder for IO sandboxing (#188657)
#184545 default-enables the IO sandbox in assert-builds. This causes
Clang using Polly to crash (#188568).
The issue is that `PassBuilder` uses `vfs::getRealFileSystem()` by
default which is considered a IO sandbox violation in the Clang process.
With this PR store the VFS from the `PassBuilder` from the original
`registerPollyPasses` call for creating other `PassBuilder` instances.
This PR also adds infrastructure for running Polly in `clang` (in
addition in `opt`). `opt` does not enable the sandbox such that we need
separate tests using Clang.
Closes: #188568

tex-l3experimental: update to 2025.76637
- Add `set` into function names for adjusting drawing state, e.g.
`\draw_set_linewidth:n` replacing `\draw_linewidth:n`
- Removed `l3str-format` package: integrated into `l3kernel`
science/orthanc: Use unversioned dcmtk DATADIR
The dcmtk port's DATADIR includes PKGVERSION in the directory
name, e.g. PREFIX/share/dcmtk-3.7.0. Starting with dcmtk-3.7.0_1,
a symlink to PREFIX/share/dcmtk is also installed, so that consumers
like orthanc, which need to access the dcmtk dictionary files, won't
break every time dcmtk is upgraded.
This commit removes the dcmtk version from the orthanc config to
use the symlink and avoid future breakage.
tex-l3kernel{,-doc}: update to 2025.77438
- Implementation of `\tl_if_regex_match:nN(TF)`
- Usage of logical AND (`&&`) in `l3fp` inside alignments
- Fix `\peek_regex_remove_once:nTF` and `\peek_regex_remove_once:NTF`
on reinserting special token `{` or `}`
Re-factor delay() on m68k.
We've settled on a blend of the amiga version and the mvme68k version.
Specifically, the amiga flavor takes a usec arg and applies the scaling
factor in delay() itself, whereas the the mvme68k flavor scaled the argument
in a macro before calling _delay() to do the work. Presumably this was to
take advantage of constant-folding, because the argument to delay() is
often a constant.
We instead scale inside delay() because, hey, it's delay() executing a
couple of additional instructions isn't going to kill us. Also, it allows
for better diagnostic checking of delay values without exposing that in
the ABI.
We picked the 68060-friendly scaling factor of 1024 (shift-by-10) rather
than 256 (shift-by-8). Macros to estimate the delay_divisor for a given
CPU type (20/30, 40, 60) using the correct scaling factor are provided to
make everything easier, as is a "weighting" macro that can be used when
calibrating the delay_divisor against a known timing source (explained in

[SLP] Check if potential bitcast/bswap candidate is a root of reduction
Need to check if the potential bitcast/bswap-like construct is a root of
the reduction, otherwise it cannot represent a bitcast/bswap construct.
Fixes #189184
