profiling for 6.2.2

[Serge D. Mechveliani]

Dear GHC developers,

I recall that there is also desirable to have in the official  
ghc-6.2.2 
                                     a reliable pro-filing  
(for the time cost centers, for -O).

Although I do not test it right now, and skipping it would not 
cause a tragedy for me, it still will be nice if you arrange this in  
ghc-6.2.2.

With kind regards,
