configure.ac: Remove long long and __int64 type checks...

2014-05-26  Richard Biener  <rguenther@suse.de>

	libcpp/
	* configure.ac: Remove long long and __int64 type checks,
	add check for uint64_t and fail if that wasn't found.
	* include/cpplib.h (cpp_num_part): Use uint64_t.
	* config.in: Regenerate.
	* configure: Likewise.

	gcc/
	* configure.ac: Drop __int64 type check.  Insist that we
	found uint64_t and int64_t.
	* hwint.h (HOST_BITS_PER___INT64): Remove.
	(HOST_BITS_PER_WIDE_INT): Define to 64 and remove
	__int64 case.
	(HOST_WIDE_INT_PRINT_*): Remove 32bit case.
	(HOST_WIDEST_INT*): Define to HOST_WIDE_INT*.
	(HOST_WIDEST_FAST_INT): Remove __int64 case.
	* vmsdbg.h (struct _DST_SRC_COMMAND): Use int64_t
	for dst_q_src_df_rms_cdt.
	* configure: Regenerate.
	* config.in: Likewise.
