Retrieve segment registers on Windows amd64
For amd64, CONTEXT_FULL does not contain CONTEXT_SEGMENTS, which seems
to be needed to retrieve all the segment registers. Add it explicitly,
with a little de-cruftification.
The value of the segment registers isn't terribly useful on amd64, but
at least this makes the output of 'info registers' correct.
Before:
(gdb) i r cs ss ds es fs gs
cs 0x33 51
ss 0x2b 43
ds 0x0 0
es 0x0 0
fs 0x0 0
gs 0x0 0
After:
(gdb) i r cs ss ds es fs gs
cs 0x33 51
ss 0x2b 43
ds 0x2b 43
es 0x2b 43
fs 0x53 83
gs 0x2b 43
