/**
Retrieves CPUID information.
Executes the CPUID instruction with EAX set to the value specified by Index.
This function always returns Index.
If Eax is not NULL, then the value of EAX after CPUID is returned in Eax.
If Ebx is not NULL, then the value of EBX after CPUID is returned in Ebx.
If Ecx is not NULL, then the value of ECX after CPUID is returned in Ecx.
If Edx is not NULL, then the value of EDX after CPUID is returned in Edx.
This function is only available on IA-32 and x64.
@param Index The 32-bit value to load into EAX prior to invoking the CPUID
instruction.
@param RegisterEax A pointer to the 32-bit EAX value returned by the CPUID
instruction. This is an optional parameter that may be NULL.
@param RegisterEbx A pointer to the 32-bit EBX value returned by the CPUID
instruction. This is an optional parameter that may be NULL.
@param RegisterEcx A pointer to the 32-bit ECX value returned by the CPUID
instruction. This is an optional parameter that may be NULL.
@param RegisterEdx A pointer to the 32-bit EDX value returned by the CPUID
instruction. This is an optional parameter that may be NULL.
@return Index.
