0df99ad4 - Remove unnecessary __at_align32__ in int_elementwise_binary_256 (#45470)

Remove unnecessary __at_align32__ in int_elementwise_binary_256 (#45470) Summary: They were added in 4b3046ed286e92b5910769bf97f2bc6a1ad473d1 based on a misunderstanding of `_mm256_storeu_si256`, but they are actually unnecessary. The [document][1] of `_mm256_storeu_si256` says: > Moves values from a integer vector to an **unaligned** memory location. In this case, it's better to remove the `__at_align32__` qualifier to leave the compiler and linker more flexibility to optimize.
