* fold-const.c (fold_checksum_tree <case 't'>): Only
look at TREE_VALUES if the EXPR is an ENUMERAL_TYPE.
Only look at TYPE_MIN_VALUE and TYPE_MAX_VALUE if
EXPR is an INTEGERAL_TYPE or a scalar float type.

* fold-const.c (omit_two_operands): New function.
* tree.h (omit_two_operands): Prototype here.
* builtins.c (fold_builtin_unordered_cmp): New function to lower
C99 unordered comparison builtins to the appropriate tree nodes.
(fold_builtin_1): Use fold_builtin_unordered_cmp to lower
BUILT_IN_ISGREATER, BUILT_IN_ISGREATEREQUAL, BUILT_IN_ISLESS,
BUILT_IN_ISLESSEQUAL and BUILT_IN_ISLESSGREATER. Manually lower
BUILT_IN_ISUNORDERED comparisons to an UNORDERED_EXPR tree node.
(simplify_builtin_memcmp, simplify_builtin_strncmp,
simplify_builtin_strncat, simplify_builtin_strspn): Use the new
omit_two_operands function to build the required COMPOUND_EXPRs.
