    x86/Intel: don't accept memory operands with J*CXZ and LOOP*

    PR gas/31887

    Like for, in particular, J<cc> such should be rejected. Simplify the
    respective conditional in i386_intel_operand(), leveraging that
    JumpAbsolute will never occur in the first template of a mnemonic-
    specific group (thus making it unnecessary to exclude that one case).

    At this occasion do the same simplification later in the function as
    well: The resulting two operands will uniformly be invalid for all
    mnemonics other than CALL and JMP (and their AT&T counterparts, which
    we've been wrongly accepting in Intel syntax) anyway.
