Add a test that all perf metrics (for your architecture) are parsable with the simple expression parser. Attempt to parse all events in metrics but only fail if the metric is for the current CPU. Fix bugs in the expr parser, x86 and powerpc metrics. Improve debug messages around add PMU config term failures.
v3 adds parse event testing of ids and improves debug messages for add PMU. These messages are paticular visible with 'perf test 10 -vvv'. It moves the testing logic from tests/expr.c to tests/pmu-events.c as suggested by John Garry <john.ga...@huawei.com>. v2 adds Fixes tags to commit messages for when broken metrics were first added. Adds a debug warning for division by zero in expr, and adds a workaround for id values in the expr test necessary for powerpc. It also fixes broken power8 and power9 metrics.
