Log message:
        PR target/24428
        * config/i386/i386.c (legitimate_constant_p): Check
        SYMBOL_REF_TLS_MODEL directly.  Don't fallthru to SYMBOL_REF
        if LABEL_REF.
        (legitimate_pic_operand_p): Test SYMBOL_REF_TLS_MODEL directly.
        (legitimate_pic_address_disp_p): Reorg CONST checking to make
        sure SYMBOL_REF_TLS_MODEL is tested.  Test SYMBOL_REF_TLS_MODEL
        directly.
        (print_operand_address): Likewise.
        * config/i386/predicates.md (x86_64_immediate_operand): Test
        SYMBOL_REF_TLS_MODEL properly inside CONST.
        (x86_64_zext_immediate_operand): Likewise.
        (global_dynamic_symbolic_operand, local_dynamic_symbolic_operand,
        initial_exec_symbolic_operand, local_exec_symbolic_operand): Remove.
        * config/i386/i386-protos.h: Remove predicates.md entries.
