Hopefully I won't get flamed for this: insert a few more #if defined(I486_CPU)

Browse Source 
and #if defined (I586_CPU) thingies into identifycpu() so that we only
compile in what's actually needed for a given CPU. So far as I can tell,
none of my 386 machines generate a cpu_vendor code, so I made the extra vendor
and feature line conditional on I486_CPU and I586_CPU. (Otherwise we
print out a blank line which looks silly.)
