Evaluate condition arguments with the correct type.

Processing of a cond_expr requires that a range of the correct type for the
operands of the cond_expr is passed in.

	PR tree-optimization/106556
	gcc/
	* gimple-range-gori.cc (gori_compute::condexpr_adjust): Use the
	  type of the cond_expr operands being evaluted.

	gcc/testsuite/
	* gfortran.dg/pr106556.f90: New.
