Add all segment registers for the amd64 CPU to struct reg and mcontext.
To keep these structures ABI-compatible, half the size of r_trapno,
r_err, mc_trapno, mc_flags.
Add fsbase and gsbase to mcontext on both amd64 and i386.
Add flags to amd64 mcontext to indicate that it contains valid segments
or bases.
