Rollup merge of #137149 - Noratrieb:wtf-is-this-target, r=RalfJung

Remove SSE ABI from i586-pc-windows-msvc

As an i586 target, it should not have SSE. This caused the following warning to be emitted:

```
warning: target feature `sse2` must be enabled to ensure that the ABI of the current target can be implemented correctly
  |
  = note: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
  = note: for more information, see issue #116344 <rust-lang/rust#116344>

warning: 1 warning emitted
```

see #116344.
