Come up with jump_table ratio constants used in jump_table_cluster.
2018-06-28 Martin Liska <mliska@suse.cz>
* tree-switch-conversion.c (jump_table_cluster::can_be_handled):
Use newly introduced constants.
* tree-switch-conversion.h (struct jump_table_cluster):
Define max_ratio_for_size and max_ratio_for_speed.
