re PR tree-optimization/21004 (gcc.dg/builtins-53.c fails) 

PR tree-optimization/21004
	* convert.c (convert_to_integer): Convert ceilf, ceill, floorf
	and floorl in c99 mode only.
	* builtins.c (expand_builtin_int_roundingfn): Assert that
	fallback_fndecl is not NULL_TREE.

	PR tree-optimization/21004
	* gcc.dg/builtins-53.c: Include builtins-config.h.
	Check floorf, ceilf, floorl and ceill transformations
	only when HAVE_C99_RUNTIME is defined.
