[PATCH 1/2] perf/probe: verify instruction/offset in perf beforeadding a uprobe

[Prashanth Nageshappa]

To verify instruction/offset in perf, before adding a uprobe we
need to use arc/x86/lib/insn.c from perf code. Since perf Makefile
enables -Wswitch-default flag it causes build warnings/failures. This
patch is to address the build warnings in insn.c.
