7481cad474 selftests/powerpc: Add a test of counting larx/stcx 
This is based on the count_instructions test.

However this one also counts the number of failed stcx's, and in
conjunction with knowing the size of the stcx loop, can calculate the
total number of instructions executed even in the face of
non-deterministic stcx failures.

cb96143def 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.
