print_AMD_foo() functions.
- Add a brand name table for the brand index provided on Intel CPU's in
%ebx after cpuid 1.
- For Intel CPUs, if we don't get a processor name from the extended cpuid
then use the brand index in cpuid_cpuinfo to pick a name from the brand
table and copy that name into cpu_brand.
- Replace the duplicated code to use the extended cpuid to replace
cpu_model with the processor name in the AMD and Transmeta sections of
printcpuinfo() with generic code that replaces cpu_model with
cpu_brand if cpu_brand is not an empty string. We also trim leading
spaces from cpu_brand prior to doing this since at least some processor
names (notably those of Intel CPUs) have leading spaces in the name.
- Give print_AMD_features() its own private regs[] array since
printcpuinfo() doesn't use the one it has anymore.
