Fix profile_probability quality of switch

This fixes ages old bug I noticed only now where switch cases, in situation
prediction is completely missing, gets all equal probability that should be
GUESSED instead of ADJUSTED.

gcc/ChangeLog:

	* predict.cc (set_even_probabilities): Set quality to guessed.
