Log:
    compiler: additional lvalue/rvalue context fixes
    
    Fix lvalue/rvalue context mixup Set_and_use_temporary_expression's
    do_get_backend() method. Enhance Mark_lvalue_varexprs to handle
    conversions and temporary reference expressions, since occasionally
    the front end emits code such as "deref(conv(tempref)) = ...".
