    libc: Allow more complex expressions for CALL_BLOCK first argument
    
    For the case where the compiler supports blocks we only allow the first
    expression to have an operator if it has as high precedence as a
    function call, which for blocks effectively means member access and
    subscripting only, not even a dereference nor a cast. Parenthesise this,
    as is the case for the missing compiler support case, so that it's more
    general.
