Windows 7/8.1 to 10 upgrade - CPU check

[Torinde]

32-bit CPUs without PAE will have problems with Win10 (maybe also worth to issue a warning on CPUs without NX).
64-bit CPUs without CMPXCHG16B and and maybe without LAHF/SAHF will have problems with Win10 (maybe also worth to issue a warning on CPUs without PrefetchW).
GPUs without WDDM drivers - maybe worth issue a warning.

SSE2 also warrants a check/warning and it seems you have that already: e8d91ad
