* config/i386/i386.c (output_set_got) [TARGET_MACHO]: Adjust to emit a
second label for nonlocal goto receivers. Don't output pic base labels
unless we're producing PIC; mark that action unreachable().

PIC base reg.
* config/darwin-protos.h (machopic_should_output_picbase_label): New.
* gcc/config/darwin.c (emitted_pic_label_num): New GTY.

case.
(machopic_should_output_picbase_label): New.
