Segment register reading on Windows targets.
This patch makes sure that the value of segment registers are
read properly as 16bit values on Windows.
gdb/ChangeLog:
* windows-nat.h (segment_register_p_ftype): New typedef.
(windows_set_segment_register_p): Add declaration.
* windows-nat.c (segment_register_p): New static global.
(windows_set_segment_register_p): New function.
(do_windows_fetch_inferior_registers): Add special handling
for segment registers.
* amd64-windows-nat.c: #include "amd64-tdep.h".
(amd64_windows_segment_register_p): New function.
(_initialize_amd64_windows_nat): Call windows_set_segment_register_p.
* i386-windows-nat.c: #include "i386-tdep.h".
(i386_windows_segment_register_p): New function.
(_initialize_i386_windows_nat): Call windows_set_segment_register_p.
