darwin.h: Don't include darwin-sections.def to declare global variables...
* config/darwin.h: Don't include darwin-sections.def to declare
global variables; instead create darwin_section_enum.
(darwin_section_enum): New.
(darwin_sections): New.
* config/darwin.c: Don't include darwin-sections.def to define
global variables.
(darwin_sections): New.
(output_objc_section_asm_op): Rewrite to take advantage of
darwin_sections.
(darwin_init_sections): Rewrite to use darwin_sections.
(machopic_output_indirection): Update for darwin_sections array.
(machopic_select_section): Likewise.
(machopic_select_rtx_section): Likewise.
(machopic_asm_out_constructor): Likewise.
(machopic_asm_out_destructor): Likewise.
(darwin_file_end): Likewise.
* config/rs6000/rs6000.c (machopic_output_stub): Likewise.
* config/i386/i386.c (machopic_output_stub): Likewise.
