perf/x86: Fix PEBS instruction unwind
commit 57d1c0c03c6b48b2b96870d831b9ce6b917f53ac upstream.
Masami spotted that we always try to decode the instruction stream as
64bit instructions when running a 64bit kernel, this doesn't work for
ia32-compat proglets.
Use TIF_IA32 to detect if we need to use the 32bit instruction
decoder.
