(ia64_cannot_force_const_mem): New.
(tls_symbolic_operand_type): New.
(ia64_legitimate_constant_p): New.
(ia64_expand_load_address): Return true on success. Improve
checks for when we should not split.
(ia64_expand_tls_address): New addend operand. Distribute it
as appropriate to the tls_kind. Delay referencing gp.
(ia64_expand_move): Split symbolic addend as necessary. Handle
tls symbols with addends.
