re PR tree-optimization/21088 (VRP passes fold the type of operands of a comparison)
PR tree-optimization/21088
* fold-const.c (fold_unary, fold_binary, fold_ternary):
Export.
* tree-vrp.c (compare_values): Use fold_binary to compare
pointers. Use boolean_type_node as the type of a comparison
expression being folded.
* tree.h: Add prototypes for fold_unary, fold_binary,
fold_ternary.
