Fix AO_compare_double_and_swap_double_full for gcc-4.2.1/x86 in PIC mode

* src/atomic_ops/sysdeps/gcc/x86.h
(AO_compare_double_and_swap_double_full): Use EDI register for
"new_val1" argument in PIC mode only for GCC 4.3+ to workaround
a problem with older compiler versions (e.g., GCC 4.2.1 [FreeBSD])
that do not recognize 'D' as a valid register specification; update
comment.
