[PATCH v3 3/3] selftests: Add test of PMU instruction counting on powerpc

This commit adds a test of instruction counting using the PMU on powerpc. Although the bulk of the code is architecture agnostic, the code needs to run a precisely sized loop which is implemented in assembler. Signed-off-by: Michael Ellerman --- v2,3: No change
