[clang-doc] Change highlight.js theme for light or dark themes (#181317)
Adds another `<link>` tag to load in a dark theme for highlight.js. The
appropriate theme is then loaded for the current system theme. Using a
dark theme for highlight.js in dark mode makes for a much better user
experience since declaration text has a higher contrast compared to the
dark background.
[RISCV][NFC] Fix UBSan issue in ISel (#181422)
If `int Imm` is `INT64_MIN`, then negating this value overflows, which
is undefined behaviour. This adds this case to the tests, and avoids
this case.

[Github] Account for cross-repo PRs in prune-unused-branches (#181232)
Some users (as reported in the discourse thread) use user branches
purely as a diff base for cross repo pull requests. This patch makes it
so that we do not delete branches that are used in this way.
sys/compat/freebsd32: Fix i386 compilation
The compile assertion now failing is due to the change '__int64_t' =>
'__int32_t' as the type of 'time32_t' on i386, which is the correct
value. The use of 'freebsd32.h' on i386 may seem strange, but it comes
from 'kern_umtx.c' including it unconditionally as it needs 'struct
umutex32'.

LowerTypeTests: Remove the optimization for llvm.cond.loop.
Because in the new IR pattern for conditional traps the llvm.cond.loop
is generated late, the LowerTypeTests pass will never see it, so we no
longer need to be able to optimize it. Therefore, remove the code for
optimizing it.
This reverts commit 1de721c414407f4b92d3e2458ce9ca38563cef9c.

Add llvm.looptrap intrinsic.
The '``llvm.looptrap``' intrinsic is equivalent to
``llvm.cond.loop(true)``, but is also considered to be ``noreturn``,
which enables certain optimizations by allowing the optimizer to
assume that a branch leading to a call to this intrinsic was not
taken. A late optimization pass will convert this intrinsic to either
``llvm.cond.loop(true)`` or ``llvm.cond.loop(pred)``, where ``pred``
is a predicate for a conditional branch leading to the intrinsic call,
if possible.

[libc++] Increase the minimum deployment target on macOS to 11.0 (#176094)
#166172 moved the effective minimum deployment target on macOS to 10.15
(because `aligned_alloc` is not defined before that in the C stdlib),
and indeed, it was mentioned in that PR that libc++ only supports macOS
11 and later.
This PR rectifies the documentation and the code to reflect the actually
supported deployment targets on macOS. See [1] for additional discussion
about this.

security/libgcrypt: Fix Curve25519 key validation
Starting with version 1.12.0, libgcrypt was failing to validate

https://dev.gnupg.org/T8094 to fix the problem.

[llubi] Return void for `InstExecutor::visit*` methods. NFC. (#181421)
The status is now maintained inside of `setResult` and other helper
functions. So we don't need to propagate the error.

[clang][deps] Extract service config into a struct (#181405)
Adding new configuration knobs in the scanner is fairly painful now,
especially with a diverging downstream. This patch extracts what was
previously passed into the service constructor into a struct. This
encourages one knob customization per line, reduces difficult merge
conflicts, `/*ArgName=*/`-style comments with copy-pasted defaults, etc.
[RISCV] Combine ADDD(lo, hi, x, 0) -> WADDAU(lo, hi, x, 0). Combine WADDAU (WADDAU lo, hi, x, 0), y, 0 -> WADDAU lo, hi, x, y (#181396)
WADDAU is rd += zext(rs1) + zext(rs2)
If we only have 1 32-bit input can force rs2 to avoid zeroing the upper
part of a register pair to use ADDD.
Unfortunately, WADDAU clobbers rd so it might need a GPRPair copy
if we need the old value of rd. We might need to look into that in
the future. Maybe we could have convertToThreeAddress could turn
it back into ADDD+WADDU or ADDD+LI.
