[TableGen] Emit the primary input file in -d depfile output (#197061)
This fixes a bug where old, but still supported, versions of CMake and
ninja perpetually consider zero-include tablegen files to be out of
date. It also matches what Clang and GCC do for regular C compilations.
When a .td input has no `include` directives, the depfile produced by
`-d` contains only `<output>:` followed by zero dependencies. My version
(3.27) of CMake's `cmake_transform_depfile` step then writes a 0-byte
file, which old versions of ninja treat as a missing depfile and re-run
the rule on every incremental build (e.g. Attributes.td, ValueTypes.td).
Here's the effect on Attributes.inc.d:
```
$ cat ./build/include/llvm/IR/Attributes.inc.d
Attributes.inc:
# switch branches and rebuild...
$ cat ./build/include/llvm/IR/Attributes.inc.d

[Instrumentor] Allow multiple config files with different filters
To instrument different functions in different ways we allow to provide
multiple config files now. Each file will result in one instrumentation
run. Multiple files can be passed via command line option or listed in
a "summary" file that is passed via command line option (to keep the
command length managable).
[Instrumentor] Add a global function regexp to limit the instrumentation
Only functions that match the "function_regex" will be instrumented,
or if they have the instrumentation attribute.
[Instrumentor] Add unreachable support; unreachable stack trace printing
Allow to instrument unreachable and provide a use case for stack trace
printing.

net/samba423: Fix SIGABRT in bsd_attr_list()
After FORTIFY_SOURCE was added for https://bugzilla.samba.org/show_bug.cgi?id=16040, which landed in Samba 4.23.7, the net/samba423 port started crashing quite soon after startup.
It turns out that bsd_attr_list() does a number of overlapping strncpy() calls, and this is undefined behavior.

[clang-tidy][docs] Remove outdated Phabricator reference (#196997)
Removed the old Phabricator mention from the clang-tidy contributing
guide. Since LLVM uses GitHub for code review now, this updates the
wording to match the current contribution workflow.
Fix signed overflow in ieee80211_40mhz_valid_secondary_below().
The secondary_chan variable should be uint8_t instead of int8_t,
matching ieee80211_40mhz_valid_secondary_above().

if_media: Claim 10BASE-T1S and 10BASE-T1L constants
These are two single-pair Ethernet (SPE) variants that run at 10 Mbps.
10BASE-T1S has automotive origins and supports multiple nodes on up to
25m of cable. 10BASE-T1L is intended for building and industrial
automation and supports long-distance point to point links of over 1km.
