Const-correctness of gimple_call_builtin_p

gcc/
2014-05-07  David Malcolm  <dmalcolm@redhat.com>

	* gimple.h (gimple_builtin_call_types_compatible_p): Accept a
	const_gimple, rather than a gimple.
	(gimple_call_builtin_p): Likewise, for the three variants.

	* gimple.c (gimple_builtin_call_types_compatible_p): Likewise.
	(gimple_call_builtin_p): Likewise, for the three variants.
