        (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.
        * config/ia64/ia64-protos.h: Update.
        * config/ia64/ia64.h (CALL_REALLY_USED_REGISTERS): False for r0,
        p0, f0, f1, and r13.
        (LEGITIMATE_CONSTANT_P): Move to ia64_legitimate_constant_p.
        * config/ia64/ia64.md (UNSPEC_DTPMOD): New.
        (symbolic_operand splitter): Pass everything through
        ia64_expand_load_address and FAIL or DONE as appropriate.
        (load_fptr): Only accept after reload.
