  -----------
  [clang-tidy] Fix crash in bugprone-misplaced-pointer-arithmetic-in-alloc (#224509)

This commit checks for an empty constructor argument list before
accessing its last element.

Reproducer at: https://godbolt.org/z/Tfvnbhx19

AI Usage: the issue was found by Grok 4.6. Although IMO this is a pretty
uncommon/rare case, less crash-on-valid is always better.
