Subject: [PATCH 3/3] perf beauty: Move arch/x86/include/asm/irq_vectors.h copy out of the directory used to build perf

From: Arnaldo Carvalho de Melo <acme@...hat.com>

It is used only to generate string tables, not to build perf, so move it
to the tools/perf/trace/beauty/include/ hierarchy, that is used just for
scrapping.

This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.

No other tools/ living code uses it.
