x86/emul: Correct the decoding of SReg3 operands

REX.R is ignored when considering segment register operands, and needs masking
out first.

While fixing this, reorder the user segments in x86_segment to match SReg3
encoding.  This avoids needing a translation table between hardware ordering
and Xen's ordering.
