Remove getPrefTypeAlign calls and use only the alloca's explicit alignment, since the type may not be semantically useful, there is no useful reason to change alignment to support it. The alloca's explicit alignment (from getAlign()) is already optimally correct; we don't need to derive alignment from the allocated type. Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>
