When using CreateProcessA to execute a 32-bit .NET/Mono application (which is IL-only) the process is always launched as a 32-bit process under Wine; but under Windows it is launched as a 64-bit process.
This patch changes Wine's behaviour to match Windows.

You'd need some way to handle ARM64 too. Also you probably want to update pe_info->cpu instead of adding #ifdefs everywhere it's used.
