cselib.c (clear_table): Rename to cselib_clear_table.

	* cselib.c (clear_table): Rename to cselib_clear_table.
	* cselib.h (cselib_clear_table): Add prototype.
	* gcse.c (gcse_main): Make 'f' argument unused.
	(alloc_gcse_mem): Do not walk the insn chain, walk the contents
	of each basic block instead.
	(compute_sets, compute_hash_table_work): Likewise.
	(constprop_register): Change int 'alter_jumps' argument to bool.
	(do_local_cprop): Likewise.
	(local_cprop_pass): Likewise.  Also walk basic blocks instead of
	the insn chain.  Explicitly clear the cselib tables after finishing
	one basic block.  Make sure there are no unterminated libcall blocks.
	Update compute_sets call.
	(cprop): Walk basic blocks instead of the insn chain.
	(one_cprop_pass, compute_ld_motion_mems, compute_store_table):
	Likewise.
	(bypass_jumps): Update alloc_gcse_mem, compute_sets, and
	one_cprop_pass calls.
