Support for 64-bit location_t: toplev parts

With the upcoming move from 32-bit to 64-bit location_t, the recommended
number of range bits will change from 5 to 7. line-map.h now exports the
recommended setting, so use that instead of hard-coding 5.

gcc/ChangeLog:

	* toplev.cc (general_init): Replace hard-coded constant with
	line_map_suggested_range_bits.
