[PATCH 2/3] x86: drop a few redundant EVEX-related checks

[Jan Beulich]

vex.b can only be set when vex.evex is also set. Similarly vex.evex can
only be set when need_vex is also set.

	* i386-dis.c (putop): Drop need_vex check when also checking
	vex.evex.
	(intel_operand_size, OP_E_memory): Drop vex.evex check when also
	checking vex.b.
