As a result of Bug#57609 (in 5.5.8), performance_schema table names now are lowercase.

But SHOW ENGINE PERFORMANCE_SCHEMA STATUS still displays the table names in uppercase.

How to repeat:
*************************** 1. row ***************************
  Type: performance_schema
Status: 136
*************************** 2. row ***************************
  Type: performance_schema
Status: 3000
*************************** 3. row ***************************
  Type: performance_schema
Status: 120
*************************** 4. row ***************************
  Type: performance_schema
Status: 10000

Suggested fix:
Table names should be lowercase.

      Bug#58798 SHOW ENGINE PERFORMANCE_SCHEMA STATUS: incorrect table lettercase
      Before this fix, the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS
      used uppercase to name performance schema tables.
      This is inconsistent since performance schema tables have been renamed to lowercase.
      Also, an old table 'PROCESSLIST' was still visible, 
      even after this table got renamed to 'threads'.
      This fix:
      - correctly uses lowercases in the output, to match the current naming.
      - replaced 'PROCESSLIST' with 'threads'.
      Tested the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS manually.
      No automated test cases can be written for this, 
      since the output is too platform dependent (sizes).
