    C-Sky: use is_whitespace()
    
    Wherever blanks are permissible in input, tabs ought to be permissible,
    too. This is particularly relevant when -f is passed to gas (alongside
    appropriate input). Also switch ISSPACE() uses over. At the same time
    use is_end_of_stmt() instead of kind-of-open-coded checks.
