BR 3392227: Remove SB flag from SHIFT rm,imm

Browse Source 
Remove the SB flag from the rm,imm forms of the shift/rotate
instructions; presumably the intent was to mark the immediate as a
byte immediate, but it instead caused the memory operand to be
accepted without a size, but generate the incorrect code as a result.

Note: it would be good to modify the UNITY filter so that the explicit
form:

	shl eax,byte 1

... forces the imm form rather than the ,1 form.
