Rollup merge of #43159 - cuviper:ptr-swap-simd, r=arielb1
Disable big-endian simd in swap_nonoverlapping_bytes This is a workaround for #42778, which was git-bisected to #40454's optimizations to `mem::swap`, later moved to `ptr` in #42819. Natively compiled rustc couldn't even compile stage1 libcore on powerpc64 and s390x, but they work fine without this `repr(simd)`. Since powerpc64le works OK, it seems probably related to being big-endian. The underlying problem is not yet known, but this at least makes those architectures functional again in the meantime. cc @arielb1
