Subject: [PATCH 0/8] perf metric fixes and test

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.

Ian Rogers (8):
  perf expr: unlimited escaped characters in a symbol
  perf metrics: fix parse errors in cascade lake metrics
  perf metrics: fix parse errors in skylake metrics
  perf expr: allow ',' to be an other token
  perf expr: increase max other
  perf expr: parse numbers as doubles
  perf expr: debug lex if debugging yaxx
  perf test: add expr test for pmu metrics
