[PATCH v3 0/1] MR3294: wow64win: Always use NtUserSetWindowLongPtr() for GWLP_WNDPROC.

[Sven Baars (＠sbaars)]

This fixes SetWindowLongPtr on WoW64. On 32-bit, we have

```
#define                       SetWindowLongPtrA SetWindowLongA
#define                       SetWindowLongPtrW SetWindowLongW
```

meaning that on WoW64, all pointers passed would be padded with `0xffffffff` (because they are treated as LONG), and this is the cause of many of the failing WoW64 tests. This fixes that behavior. I'm not sure if this is the right place to fix it though.
