	gcc            : ChangeLog cse.c 

Log message:
	* cse.c: Include hashtab.h instead of splay-tree.h
	(struct cse_reg_info): No longer use variant union.  Add new
	field "regno".  All references changed to avoid union.
	(cse_reg_info_used_list, cse_reg_info_used_list_end): New variables.
	(free_cse_reg_info): Remove.
	(hash_cse_reg_info, cse_reg_info_equal_p): New functions.
	(get_cse_reg_info): Revamp to use expandable hash tables instead
	of splay trees.  Initialize new fields in cse_reg_info structure.
	(new_basic_block): Similarly.
