[PATCH 3/6] perf tests: Add misc instructions to x86 instruction decoder test

[Adrian Hunter <adrian.hunter@intel.com>]

x86 instruction decoder is used for both kernel instructions and user space
instructions (e.g. uprobes, perf tools Intel PT), so it is good to update
it with new instructions.

Add instructions to x86 instruction decoder test:

	User Interrupt

		clui
		senduipi
		stui
		testui
		uiret

	Prediction history reset

		hreset

	Serialize instruction execution

		serialize

	TSX suspend load address tracking

		xresldtrk
		xsusldtrk

A subsequent patch adds the instructions to the instruction decoder.

Example:

  $ perf test -v "x86 instruction decoder" |& grep -i hreset
  Failed to decode length (4 vs expected 6): f3 0f 3a f0 c0 00    	hreset $0x0
  Failed to decode length (4 vs expected 6): f3 0f 3a f0 c0 00    	hreset $0x0
