* fold-const.c (fold) <UNORDERED_EXPR, ORDERED_EXPR, UNLT_EXPR,
UNLE_EXPR, UNGT_EXPR, UNGE_EXPR, UNEQ_EXPR, LTGT_EXPR>: Add
constant folding for unordered comparison tree nodes. If both
operands are real constants, call fold_relational_const. If either
operand is a NaN, evaluate the other for side-effects and return a
constant. Optimize (double)float1 CMP (double)float2 into the
equivalent float1 CMP float2.
(nondestructive_fold_binary_to_constant) <UNORDERED_EXPR,
ORDERED_EXPR, UNLT_EXPR, UNLE_EXPR, UNGT_EXPR, UNGE_EXPR, UNEQ_EXPR,
LTGT_EXPR>: Call fold_relational_const for constant operands.
(fold_relational_const): Add support for unordered comparison tree
nodes. Don't constant fold "ordered" floating point comparisons
against NaN if when flag_trapping_math is set.
* gcc.dg/unordered-2.c: New test case.
* gcc.dg/unordered-3.c: New test case.
