middle-end/106027 - fix types in needle folding

The fold_to_nonsharp_ineq_using_bound folding ends up creating invalid
typed IL which confuses later foldings.  The following fixes that.

	PR middle-end/106027
	* fold-const.cc (fold_to_nonsharp_ineq_using_bound): Use the
	type of the prevailing comparison for the new comparison type.
	(fold_binary_loc): Use proper types for the A < X && A + 1 > Y
	to A < X && A >= Y folding.

	* gcc.dg/pr106027.c: New testcase.
