All elements in a dense splat are identical, transposing it only changes

`arith.constant` of the transposed result shape.

[DA] Delete early return in accumulateCoefficientsGCD (NFCI) (#197935)

This patch resolved one TODO comment in `accumulateCoefficientsGCD`
regarding an early return. I think this early return doesn't change the
final result because:

- The presence/absence of this early return can only affect whether
`CurLoopCoeff` is set.
- Regardless the value of `CurLoopCoeff`, if `RunningGCD` equals 1, the
result of caller side while loop doesn't change.

Deleting this early return is somewhat beneficial, because it allows us
to merge `analyzeCoefficientsForGCD` into this function.

There are some helpers to inspect a value or call but not all

view of (de)allocations through a single API. To help with this, we now
read the alloc_align attribute to provide better alignment information
to users. alloc-family is used as well. Two new helpers provide argument

[clang-tidy] Fix crash in misc-static-initialization-cycle (#198155)

This commit fixes `misc-static-initialization-cycle` crashing on `catch
(...)`.

Catch-all handlers have no exception declaration, so traversal of
`CXXCatchStmt` can call `TraverseDecl(nullptr)`. The check previously
passed that null pointer to `DeclContext::containsDecl`. This commit
fixes the problem by adding a null guard.

Closes #198150
