    x86/gas: replace inappropriate assertion when parsing registers

    PR gas/30117
    Once a symbol had its expression evaluated, the "segment" of the symbol
    may be reg_section if a register is merely involved in the expression,
    not just when the expression references a "plain" register. Therefore
    the first of the assertions put in place by 4d1bb7955a8b was too strict.
    Convert it to an if() to deal with situations like this one found by
    fuzzing:

            x=s
            s=%eax+0
            y=s
            or $6,x

    In non-debug builds this also avoids potentially silently generating bad
    code.
