Add a test that all perf metrics (for your architecture) are
parsable. Fix bugs in the expr parser and in x86 metrics. Untested on
architectures other than x86.

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.
