Rename IA64_UNW_ACCESSORS to UNW_LOCAL_ONLY. Drop weak_alias() and

Browse source 
alias() macros.

(struct ia64_cursor): Rearrange order of members a bit to group
	things that logicall belong together.  Rename rp_loc to
	ip_loc.
(struct ia64_unwind_table): Drop start and end members (they are now
	in unw_ia64_table_t).
(struct ia64_reg_state): Break declaration out of declaration for
	ia64_state_record and add "next" member.
(struct ia64_state_record): Add member "labeled_states", drop
	members "stack", and "reg_state_list".
