    gas/z80: adjust .assume handling
    
    get_single_number() is (bogusly) more similar to get_absolute_expression()
    than its name says. As (per documentation) an expression is wanted here,
    use the respective function, which then also adds at least a little bit of
    error checking.
    
    While there also deal with possible stray other stuff on the line, as
    appropriate.
