[PATCH] kernel32: Launch 32-bit IL-only as 64-bit in WIN64

[Brendan McGrath]

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.
