Log message:
	* cse.c: Update comments.
	(cse_insn): When converting a conditional/computed jump into

	follows the converted jump.  Do not delete unreachable code.
	(cse_basic_block): Do not delete unreachable code.
	* toplev.c (rest_of_compilation): Move call to
	delete_trivially_dead_insns after the conditional call to
	jump_optimize.
