    Merge #1394
    
    1394: Fix parsing grammer of grouped expressions as the block tail expression r=philberty a=philberty
    
    When we want to compile a grouped expression we had a check for the
    LEFT_PAREN during the parse_expr_without_block but this can't be handled
    here since in this paticular example the grouped expressions is simply the
    lhs of the bit shift expression. This is already handled as part of
    parse_expr so we can simply remove the rule here and rely on parse_expr
    handling this.
    
    Fixes #1393
