Simon Pilgrim 6de0b55188 [DAG] TransformFPLoadStorePair - replace getABITypeAlign with allowsMemoryAccess (PR45116) ...

One of the cases identified in PR45116 - we don't need to limit load combines (in this case for fp->int load/store copies) to ABI alignment, we can use allowsMemoryAccess - which tests using getABITypeAlign, but also checks if a target permits (fast) misaligned memory loads by checking allowsMisalignedMemoryAccesses as a fallback.
