Refactoring cpuid model interaction
Patch for support CPU identification feature. Model smash on two pieces: platform-independent and dependent accordingly. The first obtains architecture details from CPU by special registers or execute instruction and filling proper structure. The second piece needs for more universality to use in independent code. Currently, platform-independent part supports only x86 cpuid(0h,01h) leafs. Signed-off-by: Alexey Gavrilov <alexey.gavrilov@mail.com>
