Restore i386 binary compatibility in Dwarf EH info.
* config/i386/i386.h (DWARF_FRAME_REGISTERS): Define as 17, the old
value of FIRST_PSEUDO_REGISTER.
* frame.h (DWARF_FRAME_REGISTERS): Default to FIRST_PSEUDO_REGISTER.
(struct frame_state): Use DWARF_FRAME_REGISTERS.
* dwarfout.c (output_reg_number): Ditto.
* dwarf2out.c (reg_number, expand_builtin_init_dwarf_reg_sizes): Ditto.
(DWARF_FRAME_RETURN_COLUMN): Default to DWARF_FRAME_REGISTERS.
