too many cpuids :p

technically, i386-cpuid.h was spawned from the gdb/testsuite/gdb.arch/i386-
cpuid.h which itself was spawned from the gcc sources (and both include the 
exception) which is why the header was retained.

then again, FSF owns both, so if we want to drop that, it shouldn't be an 
issue.  doesn't matter to me either way.
