x86: make sure all PUSH/POP honor DefaultSize
While segment registers are registers, their use doesn't allow sizing
of insns without suffix / explicit operand size specifier. Prevent
PUSH and POP of segment registers from entering that path, instead
allowing them to observe the stackop_size setting just like other
PUSH/POP and alike do.
