builtins.def (BUILT_IN_ICEIL{,F,L}, [...]): New builtin definitions.

	* builtins.def (BUILT_IN_ICEIL{,F,L}, BUILT_IN_IFLOOR{,F,L}
	BUILT_IN_IRINT{,F,L}, BUILT_IN_IROUND{,F,L}: New builtin definitions.
	* convert.c (convert_to_integer): Convert to BUILT_IN_ICEIL,
	BUILT_IN_IFLOOR, BUILT_IN_IRINT or BUILT_INT_IROUND when converting
	to integer_type_node.
	* fold-const.c (tree_call_nonnegative_warnv_p): Handle BUILT_IN_ICEIL,
	BUILT_IN_IFLOOR, BUILT_IN_IRINT and BUILT_INT_IROUND.
	* builtins.c (expand_builtin_in): Ditto.
	(mathfn_built_in_1): Ditto.
	(expand_builtin_int_roundingfn): Handle BUILT_IN_ICEIL and
	BUILT_IN_IFLOOR.
	(expand_builtin_int_roundingfn_2): Handle BUILT_IN_IRINT and
	BUILT_IN_IROUND.
	(fold_fixed_mathfn): Canonicalize BUILT_IN_ICEIL, BUILTIN_IN_IFLOOR
	BUILT_IN_IRINT and BUILT_IN_IROUND to BUILT_IN_LCEIL,
	BUILTIN_IN_LFLOOR, BUILT_IN_LRINT and BUILT_IN_LROUND on ILP32 targets.
