PR tree-optimization/25148
* tree-vrp.c (compare_values): Remove code dealing with
comparisons against type min/max value.  Honour overflow
and negative constants in code dealing with comparisons
of plus and minus expressions.
(value_inside_range): Use fold_binary with LE_EXPR and
GE_EXPR rather than compare_values.
