PR tree-optimization/19060
* tree-ssa-dom.c (extract_range_from_cond) <case LT_EXPR, GT_EXPR>:
Return 0 if op1 <= TYPE_MIN_VALUE () resp. op1 >= TYPE_MAX_VALUE ().
(simplify_cond_and_lookup_avail_expr): Add assert for dummy == 0
and handle extract_range_from_cond returning false.
* fold-const.c (fold): Optimize comparisons with min/max even for
width > HOST_BITS_PER_WIDE_INT.
* gcc.c-torture/execute/20050104-1.c: New test.
