Reduce memory requirements for ranger

Calculate block exit info upfront, and then any SSA_NAME which is never
used in an outgoing range calculation is a pure global and can bypass the
on-entry cache.

	PR tree-optimization/98174
	* gimple-range-cache.cc (ranger_cache::ssa_range_in_bb): Only push
	poor values to be examined if it isn't a pure global.
	(ranger_cache::block_range): Don't process pure globals.
	(ranger_cache::fill_block_cache): Adjust has_edge_range call.
	* gimple-range-gori.cc (gori_map::all_outgoing): New bitmap.
	(gori_map::gori_map): Allocate all_outgoing.
	(gori_map::is_export_p): No specified BB returns global context.
	(gori_map::calculate_gori): Accumulate each block into global.
	(gori_compute::gori_compute): Preprocess each block for exports.
	(gori_compute::has_edge_range_p): No edge returns global context.
	* gimple-range-gori.h (has_edge_range_p): Provide default parameter.
