x86/ucode: fix gcc uninitialised warning
This fixes the case where selected_size is never set to anything
in the loop. Whilst here, also set selected_fw to NULL so the case
of "no firmware" correctly sets everything to NULL/0.
```

[sanitizer] Fix race condition in GetNamedMappingFd with decorate_pro… (#190981)
…c_maps=1
Multi-threaded programs crash randomly when
ASAN_OPTIONS=decorate_proc_maps=1 is enabled due to filename collision
in /dev/shm.
Root Cause:
All threads use the same filename format '/dev/shm/<PID> [name]',
causing race conditions where one thread deletes a file created by
another thread, resulting in ENOENT errors.
Solution:
Add thread ID (TID) to the filename to ensure uniqueness:
- Old format: /dev/shm/<PID> [name]
- New format: /dev/shm/<PID>.<TID> [name]
This ensures each thread has a unique filename, eliminating the race

[libcxx] Remove package installation for generic-llvm-libc (#194259)
Now that these packages are installed by default in the container image,
we no longer need to install them each time we do a build.
Add ssl subdirectory to share/keys/Makefile
Without ssl in SUBDIR, the ghostbsd-cert package has no files
to install. This was fixed on releng/15.0 but not carried over.

tail(1): Fix -r (reverse) to work on pseudo filesystems
Pseudo filesystems (e.g., procfs) advertise a zero file size.
Fix reverse() to handle such a case similarly as forward() so
that '-r' works on pseudo filesystems.

[VPlan] Use RUN_VPLAN_PASS for later VPlan transforms. (#194261)
Convert a number of later VPlan transform invocations to use
RUN_VPLAN_PASS. Enables more accurate transform printing, as well as
extra verification.
This should migrate all remaining transforms that can be moved without
changes.
[LV] Add test cases where wide IV can cause spills. (#194260)
Add test cases showing cases where replacing VPWidenCanonicalIVRecipe
with VPWidenIntOrFPinductionPHIRecipe is profitable/not profitable due
to introducing spills.
[ConstantFolding] Fold byte loads from constant globals (#194074)
Handle byte types in `FoldReinterpretLoadFromConst` and
`ConstantFoldLoadFromUniformValue` so loads from constant globals fold.
lldb-dap: Fix race condition in event threads creation (#194012)
Move the registration of the SBListener to before
the event threads (`ProgressEventThread` and `EventThread`) start
This prevents a race condition where a stop event
could be missed if it was sent immediately after thread creation, which
would lead to a deadlock. It is most likely to happen under heavy CPU
load with test that fails early like
TestDAP_commands::test_command_directive_abort_on_error_init_commands.
Relevant logs.
