perf tools: Add Intel PT decoder Add support for decoding an Intel Processor Trace. Intel PT trace data must be 'decoded' which involves walking the object code and matching the trace data packets. The decoder requests a buffer of binary data via a get_trace() call-back, which it decodes using instruction information which it gets via another call-back walk_insn().

perf tools: Add Intel PT instruction decoder Add support for decoding instructions for Intel Processor Trace. The kernel x86 instruction decoder is copied for this. This essentially provides intel_pt_get_insn() which takes a binary buffer, uses the kernel's x86 instruction decoder to get details of the instruction and then categorizes it for consumption by an Intel PT decoder.
