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.

-#  need_64bit_hwint	Set to yes if HOST_WIDE_INT must be 64 bits wide
-#			for this target.  This is true if this target
-#			supports "long" or "wchar_t" wider than 32 bits,
-#			or BITS_PER_WORD is wider than 32 bits.
-#			The setting made here must match the one made in

 #  configure_default_options
 #			Set to an initializer for configure_default_options
 #			in configargs.h, based on --with-cpu et cetera.
