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.
