[PATCH GCC]Obvious change, dump min_profitable_estimate, rather than min_profitable_iters

[Bin Cheng]

Hi,
This is an obvious change to vect_estimate_min_profitable_iters.  Given the 
context, it should dump min_profitable_estimate at patch site, rather than 
min_profitable_iters.  Or I must mis-understood something in the code.
Build successfully, no test needed.  Is it OK?  I am not sure obvious change 
rule can be applied during stage4 or not.

Thanks,
bin
