PHIOPT: Fix comment before factor_out_conditional_operation

I didn't update the comment before factor_out_conditional_operation
correctly. this updates it to be correct and mentions unary operations
rather than just conversions.

Pushed as obvious.

gcc/ChangeLog:

	* tree-ssa-phiopt.cc (factor_out_conditional_operation): Update
	comment.
