x86: use generic register names in struct user_regs_struct
Switch struct user_regs_struct (defined in <asm/user.h>, which is no
longer exported to userspace) to using register names without e- or
r-prefixes for both 32 and 64 bit x86. This is intended as a
preliminary step in unifying this code between architectures.
Also, be a bit more strict in truncating 32-bit "extended" segment
register values to 16 bits.
