powerpc: emulate_step() tests for load/store instructions
Add new selftest that test emulate_step for Normal, Floating Point,
Vector and Vector Scalar - load/store instructions. Test should run
at boot time if CONFIG_KPROBES_SANITY_TEST and CONFIG_PPC64 is set.
Sample log:
emulate_step_test: ld : PASS
emulate_step_test: lwz : PASS
emulate_step_test: lwzx : PASS
emulate_step_test: std : PASS
emulate_step_test: ldarx / stdcx. : PASS
emulate_step_test: lfsx : PASS
emulate_step_test: stfsx : PASS
emulate_step_test: lfdx : PASS
emulate_step_test: stfdx : PASS
emulate_step_test: lvx : PASS
emulate_step_test: stvx : PASS
emulate_step_test: lxvd2x : PASS
emulate_step_test: stxvd2x : PASS
