This is an attempt to make the CPUID cache topology code clearer, by replacing the magic numbers in the code with #defines, and moving all the cache information to the same place in the file. I took care of comparing the assembly output of compiling target-i386/cpu.c before and after applying this change, to make sure not a single bit was changed on cpu_x86_cpuid() before and after applying this patch (unfortunately I had to manually check existing differences, because of __LINE__ expansions on object_class_dynamic_cast_assert() calls). This even keeps the code bug-compatible with the previous version: today the cache information returned on AMD cache information leaves (CPUID 0x80000005 & 0x80000006) do not match the information returned on CPUID leaves 2 and 4. The L2 cache information on CPUID leaf 2 also doesn't match the information on CPUID leaf 2. The new constants should make it easier to eventually fix those inconsistencies. All inconsistencies I have found are documented in code comments.
