    glsl: add ARB_shading_language_include support to #line
    
    From the ARB_shading_language_include spec:
    
       "#line must have, after macro substitution, one of the following
        forms:
    
           #line <line>
           #line <line> <source-string-number>
           #line <line> "<path>"
    
        where <line> and <source-string-number> are constant integer
        expressions and <path> is a valid string for a path supplied in the
        #include directive. After processing this directive (including its
        new-line), the implementation will behave as if it is compiling at
        line number <line> and source string number <source-string-number>
        or <path> path. Subsequent source strings will be numbered
        sequentially, until another #line directive overrides that
        numbering."
