[rfc]: Macros in gdbtypes

[Markus Deuling]

Hi,

in gdbtypes.h are some macros based on current_gdbarch (eg. builtin_type_void_data_ptr). This patch
replaces builtin_type_void_data_ptr by its definition in the source tree and then replaces current_gdbarch
by appropriate methods were possible.

This patch is **NOT** tested and shall no be committed right now. 

Before proceeding I want to hear from you if that's a way to go for those macros or if you would prefer s.th. else to get rid
of the current_gdbarch's in gdbtypes.h

Thanks a lot for your effort.

ChangeLog:

	* target-descriptions.c (tdesc_register_type): Replace
	builtin_type_void_data_ptr by its expression. Replace current_gdbarch
	by gdbarch.
	* target.c (default_region_ok_for_hw_watchpoint): Likewise.
	* std-regs (value_of_builtin_frame_fp_reg)
	(value_of_builtin_frame_pc_reg): Likewise.
	* spu-tdep.c (spu_register_type): Likewise.
	* sparc-tdep.c (sparc32_register_type): Likewise.

	* m88k-tdep.c (m88k_register_type): Likewise.
	* m68k-tdep.c (m68k_register_type): Likewise.
	* m32r-tdep.c (m32r_register_type): Likewise.
	* i386-tdep.c (i386_get_longjmp_target, i386_register_type): Likewise.
	* h8300-tdep.c (h8300_register_type): Likewise.
	* gnu-v3-abi.c (gnuv3_baseclass_offset, gnuv3_method_ptr_size)
	(gnuv3_make_method_ptr, gnuv3_method_ptr_to_value): Likewise.
	* cris-tdep.c (cris_register_type, crisv32_register_type): Likewise.
	* bsd-uthread.c (bsd_uthread_fetch_registers)
	(bsd_uthread_wait, bsd_uthread_find_new_threads): Likewise.
	* arm-tdep.c (arm_register_type): Likewise.
	* amd64-tdep.c (amd64_register_type): Likewise.
	* alpha-tdep.c (alpha_cannot_store_register): Likewise.

	* solib-svr4.c (LM_ADDR_FROM_LINK_MAP, LM_DYNAMIC_FROM_LINK_MAP)
	(LM_NEXT, LM_NAME, IGNORE_FIRST_LINK_MAP_ENTRY, scan_dyntag)
	(solib_svr4_r_map, solib_svr4_r_ldsomap, open_symbol_file_object)
	(svr4_fetch_objfile_link_map): Replace builtin_type_void_data_ptr by
	its expression.
	* procfs.c (procfs_address_to_host_pointer
	(procfs_can_use_hw_breakpoint): Likewise.
	* objc-lang.c (print_object_command): Likewise.
	* f-valprint.c (f77_get_dynamic_lowerbound)
	(f77_get_dynamic_upperbound): Likewise.
	* dwarf2loc.c (dwarf_expr_read_reg): Likewise.

	* auxv.c (target_auxv_parse): Likewise.
	* ada-valprint.c (ada_val_print_1): Likewise.

	* gdbtypes.h (builtin_type_void_data_ptr): Remove.
