Darwin : Fix out-of-bounds access to df_regs_ever_live.
During changes made for LRA (or, perhaps, even before) we omitted
a check that the current register we are working on is a hard reg
before we tried to note its liveness.
A stage 1 built with fsanitize=address catches this, as does any
attempt to build master with clang and -std=c++11.
gcc/ChangeLog:
* config/darwin.c (machopic_legitimize_pic_address): Check
that the current pic register is one of the hard reg set
before setting liveness.
