	* builtins.def (BUILT_IN_LCEIL, BUILT_IN_LCEILF, BUILT_IN_LCEILL)
	(BUILT_IN_LLCEIL, BUILT_IN_LLCEILF, BUILT_IN_LLCEILL): New.
	* optabs.h (enum optab_index): Add new OTI_lceil.
	(lceil_optab): Define corresponding macro.
	* optabs.c (init_optabs): Initialize lceil_optab.
	* genopinit.c (optabs): Implement lceil_optab using lceilsi2
	and lceildi2 patterns.

	* builtins.c (expand_builtin_int_roundingfn): Handle
	BUILT_IN_LCEIL{,F,L} and BUILT_IN_LLCEIL{,F,L}.
	(fold_builtin_int_roundingfn): Handle BUILT_IN_LCEIL{,F,L} and
	BUILT_IN_LLCEIL{,F,L}.
	(fold_builtin_1): Fold BUILT_IN_LCEIL{,F,L} and
	BUILT_IN_LLCEIL{,F,L} using fold_builtin_int_roundingfn.
	(mathfn_built_in): Handle BUILT_IN LCEIL and BUILT_IN_LLCEIL.
	(expand_builtin): Expand BUILT_IN_LCEIL{,F,L} and
	BUILT_IN_LLCEIL{,F,L} using expand_builtin_int_roundingfn.

	* convert.c (convert_to_integer): Convert (long int)ceil{,f,l},
	into lceil built-in function and (long long int)ceil{,f,l} into
	llceil built-in function.
	* fold-const.c (tree_expr_nonnegative_p): Add BUILT_IN_LCEIL and
	BUILT_IN_LLCEIL.
testsuite:

	* gcc.dg/builtins-53.c: Also check (int)ceil* and
	(long long int)ceil*.
