Add performance* to default global tidy checks. 

* This enables 5 performance related checks:
    performance-faster-string-find
    performance-for-range-copy
    performance-implicit-cast-in-loop
    performance-unnecessary-copy-initialization
    performance-unnecessary-value-param
* Recognize these new warnings in warn.py.
