x86: replace "anymem" checks where possible

Once operand parsing has completed, the simpler check of Operand_Mem can
be used in places where i.types[] got passed to operand_type_check().
Note that this has shown a couple of omissions of adjusting i.flags[]
when playing with i.op[] / i.types[] / i.tm.operand_types[].  Not all of
them get added here, just all of the ones needed in process_operands().
