config.gcc: Remove need_64bit_hwint.

2014-05-20  Richard Biener  <rguenther@suse.de>

	gcc/
	* config.gcc: Remove need_64bit_hwint.
	* configure.ac: Do not define NEED_64BIT_HOST_WIDE_INT.
	* hwint.h: Do not check NEED_64BIT_HOST_WIDE_INT but assume
	it to be true.
	* config.in: Regenerate.
	* configure: Likewise.

	libcpp/
	* configure.ac: Copy gcc logic of detecting a 64bit type.
	Remove HOST_WIDE_INT define.
	* include/cpplib.h: typedef cpp_num_part to a 64bit type,
	similar to how hwint.h does it.
	* config.in: Regenerate.
	* configure: Likewise.
