    modula2: remove description of fdebug-trace-quad, fdebug-trace-api and add fm2-debug-trace=
    
    This documentation fix removes the descriptions of -fdebug-trace-quad
    and -fdebug-trace-api.  It adds a description of -fm2-debug-trace=
    together with the trace alternatives: line,token,quad,all.
    
    gcc/ChangeLog:
    
            * doc/gm2.texi (Compiler options): Remove -fdebug-trace-quad.
            Remove -fdebug-trace-api.
            Add -fm2-debug-trace=.
