This is for 7u2.

Fixed 6990015: Incorrect Icache line size is used for 64 bit x86

Until 7059226 is fixed we can't use information from cpuid to determine the 
cache flashing size since flush_icache stub have to be generated before cpuid 
stub. For now I just fixed the ICache::line_size and added verification code 
into vm_version_x86. After 7059226 is fixed I will revisit this Icache code.

Thanks,
Vladimir
