[AMDGPU] Make SIShrinkInstructions pass return valid changed state (#168833)
The SIShrinkInstructions run() method currently returns "false"
unconditionally. This change makes it return the actual changed state.
[lldb/cmake] create staging directory for headers (#173427)
copy_command can either become `cmake -E copy`, which handles target
directory creation automatically, or `unifdef >` which fails without
explicitly created directory and consequently so does
version-header-fix.py later on.
[clang-tidy] Remove `allow-long-titles` option in doc8 config (#173519)
There is a bug in `doc8` where `allow-long-titles` option incorrectly
skipping non-title lines. So we have to disable it before they solve the
problem and make a new release.
MIPSr6: Set SETCC CondCode not supported by hardware to Expand (#173541)
With the current custom match rules, we may generate code like
```
cmp.ueq.s $f0, $f12, $f14
mfc1 $1, $f0
not $1, $1
mtc1 $1, $f0
sel.s $f0, $f14, $f12
jrc $ra
```
With Expand, we can get:
```
cmp.ueq.s $f0, $f12, $f14
sel.s $f0, $f12, $f14
jrc $ra
```
[libc++] Implement P1789R3: Library Support for Expansion Statements (#167184)
[P1789R3](https://isocpp.org/files/papers/P1789R3.pdf) was accepted for
C++26 through LWG motion 14 at the 2025 Kona meeting. This patch
implements it, along with tests and documentation changes.
Closes #167268

m4: avoid warnings about too-long initializer strings
Mark `digits` as `__non_string`, to avoid warnings from clang 21 similar
to:
usr.bin/m4/misc.c:123:27: error: initializer-string for character array is too long, array size is 36 but initializer has size 37 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
123 | static char digits[36] = "0123456789abcdefghijklmnopqrstuvwxyz";
