could be used again

Gabe Black fc6b2cceb4 X86: Make fixed register operands ignore register index extensions from the REX prefix. 
The only cases where this was the correct behavior are now handled with the
"B" operand type, and doing things this way was breaking some instructions,
notably a shift.

up.
