Subject: [PATCH] Support for 64-bit location_t: libgdiagnostics parts

Tweak libgdiagnostics.cc, which is necessarily sensitive to line-map
internals, to support 64-bit location_t as well.

gcc/ChangeLog:

	* libgdiagnostics.cc (struct diagnostic_manager): Use location_t(-1)
	instead of UINT_MAX to support 64-bit location_t as well.
	(diagnostic_manager::diagnostic_manager): Change hard-coded "5" to
	line_map_suggested_range_bits.
