The test fails for avr because malloc has been declared to take
an unsigned long, whereas size_t for avr is only unsigned int.

Fixed by typedef'ing __SIZE_TYPE__ to size_t and using it in the
malloc function declaration.

    If somebody writes
    
    func (s []int) _() {}
    
    we should report an error.  Before this patch we were silently
    accepting this code, because we didn't report any errors about the
    receiver if the method was a sink.
    
    This patch is unfortunately slightly complex to handle the case of
    
    func (x int) _() {}
    
    which we can only detect after define_global_names.
    
    This fixes blank1.go in the current gc testsuite.
