Since I spent some time rethinking this, just a quick note that in the next
iteration of the patchset (incoming ~soon) I decided the best thing to do is
imitate the way the backend *core-note.c files are structured (x86_corenote.c
included in x86_64_corenote.c, i386_corenote.c; likewise a new file
linux-perf-regs.c can provide the pieces for x86_64, i386 and [future-proofing]
other arches).
