Further multiarching work mostly for hppa64-*-hpux11:

        * hppa-tdep.h: New file.
        * hppa-tdep.c: #include hppa-tdep.c.
        (hppa32_num_regs): Renamed from hppa_num_regs.
        (hppa64_num_regs): New constant.
        (hppa64_call_dummy_breakpoint_offset): New constant.
        (hppa32_call_dummy_length): New constant.
        (hppa64_call_dummy_length): New constant.
        (hppa32_stack_align): Make name 32bit explicit.
        (hppa32_register_virtual_type): Likewise.
        (hppa32_extract_return_value): Likewise.
        (hppa32_use_struct_convention): Likewise.
        (hppa32_store_return_value): Likewise.
        (hppa64_register_virtual_type): New function.
        (hppa64_extract_return_value): New function.
        (hppa64_use_struct_convention): New function.
        (hppa64_store_return_value): New function.
        (hppa_frame_locals_address): Remove declaration, function does
        not exist anymore.
        (hppa_register_byte): Add support for PA64 ABI.
        (hppa_gdbarch_init): Add support for PA64 ABI.
        * hppa-hpux-tdep.c (hppa32_hpux_frame_saved_pc_in_sigtramp):
        Make name 32bit explicit.
        (hppa32_hpux_frame_base_before_sigtramp): Likewise.
        (hppa32_hpux_frame_find_saved_regs_in_sigtramp): Likewise.
        (hppa64_hpux_frame_saved_pc_in_sigtramp): New function.
        (hppa64_hpux_frame_base_before_sigtramp): New function.
        (hppa64_hpux_frame_find_saved_regs_in_sigtramp): New function.
        * config/pa/tm-hppa64.h: Remove macros that are no longer
        necessary now that the gdbarch vector is properly setup.
        Transform some macros into function calls. Some minor cleanup.
        * config/pa/tm-hppah.h: Update function calls in macros
        following the function renaming in hppa-hpux-tdep.c.
        * Makefile.in (hppa_tdep_h): New variable.
        (hppa-tdep.o): Add dependency over hppa_tdep_h.
