intel: Add perf debug for glCopyPixels() fallback checks.

Browse source 
The separate function for the fallback checks wasn't particularly
clarifying things, so I put the improved checks in the caller.  (Note that
the dropped _mesa_update_state() had already happened once at the start of
the caller)
