re PR tree-optimization/27865 (tree check failure building FreePOOMA)
PR tree-optimization/27865
* tree-vrp.c (adjust_range_with_scev): Do not use TYPE_{MIN,MAX}_VALUE
for pointer types.
* tree-scalar-evolution.c (fold_used_pointer_cast, pointer_offset_p,
fold_used_pointer, pointer_used_p): New functions.
(analyze_scalar_evolution_1): Use fold_used_pointer.
* tree-chrec.c (convert_affine_scev): Convert no-op casts correctly.
* tree-ssa-loop-ivopts.c (generic_type_for): Return integral type
for pointers.
