[MLIR][Affine] Fix null operands in simplifyConstrainedMinMaxOp (#189246)
`mlir::affine::simplifyConstrainedMinMaxOp` called
`canonicalizeMapAndOperands` with `newOperands` that could contain null
`Value()`s. These nulls came from
`unpackOptionalValues(constraints.getMaybeValues(), newOperands)` where
internal constraint variables added by `appendDimVar` (for `dimOp`,
`dimOpBound`, and `resultDimStart*`) have no associated SSA values.
Passing null Values to `canonicalizeMapAndOperands` risks undefined
behavior:
- `seenDims.find(null_value)` in the DenseMap causes all null operands
to collide at the same key, producing incorrect dim remapping.
- Any null operand that remains referenced in the result map would
propagate as a null Value into `AffineValueMap`, crashing callers that
try to use those operands to create ops.
Fix: Before calling `canonicalizeMapAndOperands`, filter null operands
from `newOperands` by replacing their dim/symbol positions in `newMap`

[mlir][IntRangeAnalysis] Fix assertion in inferAffineExpr for mod with range crossing modulus boundary (#188842)
The "small range with constant divisor" optimization in
`inferAffineExpr` for `AffineExprKind::Mod` assumed that if the dividend
range span (`lhsMax - lhsMin`) is less than the divisor, then the mod
results form a contiguous range. This is not always true, as the range
can straddle a modulus boundary.
For example, `[14, 17] mod 8`:
- Span is 3 < 8, so the old condition passed
- But `14%8=6` and `17%8=1` (wraps at 16)
- `umin=6, umax=1` → assertion `umin.ule(umax)` fails
The fix adds a same-quotient check (`lhsMin/rhs == lhsMax/rhs`) to
ensure both endpoints fall within the same modular period. When they
don't, we fall back to the conservative `[0, divisor-1]` range.

[NFC][analyzer] Eliminate SwitchNodeBuilder (#188096)
This commit removes the class `SwitchNodeBuilder` because it just
obscured the logic of switch handling by hiding some parts of it in
another source file.
Add a missing m_freem in a default (non-IPv[46]) path of tcp_respond().
This has no real effect as the protcol is already checked earlier in
the function, but might avoid issues in the future.
Remove ssl_server_legacy_first_packet()
This has not been reachable since we made the TLSv1.3 stack the default
entry point - tls13_record_layer_read_record() will send a protocol
version alert and raise an error, which means we never transition into
the legacy stack.

splash: add shutdown splash
This commit adds a shutdown splash to the existing kernel startup splash(4)
screen feature. It can be customized by providing a PNG image to the
shutdown_splash directive loader.conf(5).

[lldb][Module] Only call LoadScriptingResourceInTarget via ModuleList (#190136)
This patch is motivated by
https://github.com/llvm/llvm-project/pull/189943, where we would like to
print the "these module scripts weren't loaded" warning for *all*
modules batched together. I.e., we want to print the warning *after* all
the script loading attempts, not from within each attempt.
To do so we want to hoist the `ReportWarning` calls in
`Module::LoadScriptingResourceInTarget` out into the callsites. But if
we do that, the callers have to remember to print the warnings. To avoid
this, we redirect all callsites to use
`ModuleList::LoadScriptingResourceInTarget`, which will be responsible
for printing the warnings.
To avoid future accidental uses of
`Module::LoadScriptingResourceInTarget` I moved the API into
`ModuleList` and made it `private`.
