Eduardo Habkost 5e891bf8fd target-i386: Use #defines instead of magic numbers for CPUID cache info
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.
